DeliOne FlexiLid Food-Grade Sealing Set｜0.5mm Japanese Platinum Silicone Stretch Lids, Universal Fit for Various Sizes, Airtight Freshness Preservation｜Microwave and Dishwasher Safe

The US DeliOne FlexiLid Modular Set Food Storage System—Featuring 0.5mm-thin Japanese platinum silicone elastic lids that seal bowls, cups, and plates of various sizes with a simple stretch and press. Combined with 3° beveled modular bowls, it squeezes out excess air to prevent oxidation. Lab-tested to keep food sealed for up to 14 days and reusable over 5,000 times. Seal leftovers like fruit, meat, and meals in a second, and say goodbye to cling film and disposable plastic containers.

Starting with a "0.5mm silicone film," the DeliOne FlexiLid Modular Set completely reimagines the "lid" in your kitchen. Made from Japanese platinum liquid silicone, these elastic lids are ultra-thin, highly resilient, transparent, and glossy. They stretch easily to fit various shapes and sizes of containers, whether it's the bowls included in the set or your existing glass bowls, ceramic plates, water cups, or even half a papaya or watermelon. The matching modular bowls are designed with 3° smooth beveled edges, allowing the silicone lid to fit more snugly. A light press on the lid expels excess air, reducing contact between food and oxygen to slow down oxidation, browning, and spoilage—lab-tested to keep food fresh for up to 14 days. The set also includes an open mixing lid for spill-free whisking or mixing, and a middle layer lid that doubles as a heat-resistant mat, jar opener, or oven mitt. The non-slip bowl base ensures stability during mixing. The entire set is stackable, taking up minimal space. Materials are heat-resistant and BPA-free, making them suitable for microwaves, refrigerators, freezers, and dishwashers. Lab-tested for over 5,000 uses, this is a durable kitchen investment that is also ocean-friendly.

Do you face these issues?

• Leftover fruit, onions, or lemons wrapped in cling film still leak air, becoming discolored and dry by the next day.
• A mountain of food containers at home, but the lids never fit the bowls, taking more time to find the right lid than to cook.
• Using one bowl to marinate, mix salads, or whisk eggs, then switching to another container for storage—creating more dishes to wash.
• Using cling film, foil, and disposable containers daily, knowing it's wasteful but unable to find a convenient alternative.
• Limited kitchen cabinet space; bowls and containers of different sizes can't be stacked, leading to clutter.

Why choose the DeliOne FlexiLid Modular Set?

Most silicone stretch lids on the market are thick, heavy, lack elasticity, have low transparency, turn white and deform after a few uses, and "cover" rather than truly "seal." DeliOne uses new technology to create a 0.5mm-thin platinum silicone film that is extremely resilient and highly transparent, allowing it to easily stretch over and fit containers of various sizes and shapes while offering a clear view of the contents, eliminating the need for labels. More importantly, DeliOne doesn't just make lids; it creates a "modular system": the 3° beveled bowl edges are specifically designed for a tight silicone seal, proven by lab tests to last up to 14 days; the bowls and lids interlock for space-saving storage; and the addition of a mixing lid, multi-functional lid, and non-slip base solves prep, mixing, storage, and reheating all at once. The silicone is manufactured in Japan, BPA-free, and produced in factories working with multinational retail groups, ensuring quality and material safety.

Three Key Features

1. 0.5mm Platinum Silicone Elastic Lids × Universal Fit

The 0.5mm-thin Japanese platinum silicone film is ultra-elastic, resilient, and transparent. A single lid can stretch to fit the included modular bowls, various household bowls, cups, and plates, or even wrap directly over half a fruit. No more hunting for the right lid for every bowl.

2. 3° Beveled Seal × Air Expulsion for Anti-Oxidation

The modular bowl edges are designed with 3° smooth bevels, allowing the silicone lid to seal tightly. Simply press the lid to expel excess air, reducing oxidation, keeping fruit from browning, and meat fresh. Lab-tested to ensure a reliable 14-day leak-proof seal.

3. Versatile Use × Stackable Storage

The mixing lid with an opening allows for splash-free whisking or mixing. The middle lid acts as a heat-resistant mat or jar opener. The non-slip bowl base keeps the bowl steady. The entire set stacks neatly from largest to smallest, occupying only the space of a single bowl.

Thoughtful Design

• Japanese Platinum Silicone: Raw material made in Japan, platinum-cured, neutral in taste, BPA-free, and stays transparent without turning white after stretching.
• Lab-tested 5,000+ times: Remains elastic and retains sealing power even after 5,000+ repeated stretch and compression cycles.
• Lab-tested 14-day seal: Works with the 3° beveled bowl for reliable, long-lasting leak-proof storage.
• PP or TRITAN Bowl Options: PP bowls are lightweight and durable; TRITAN bowls are crystal clear like glass, impact-resistant, and won't crack easily.
• High-Transparency Lid: Easily view contents without opening the lid or using labels.
• Mixing Lid with Opening: Central opening allows for a whisk or blender to be inserted while the lid prevents splashing.
• Multi-functional Middle Lid: Functions as a sealing lid, heat-resistant mat, jar gripper, or oven mitt.
• Non-slip Bowl Base: Ensures stability while mixing or whisking.
• Smart Slicing/Grating System (Full Set): Metal grating/slicing plates fit perfectly over specialized bowls for neat food prep.
• Stackable Storage: The entire set nests perfectly for tidy, space-saving storage.
• All-Scenario Use: Microwave, fridge, freezer, and dishwasher safe (remove silicone lids before heating).
• Eco-friendly: Replaces cling film, foil, and disposable containers to reduce plastic waste in our oceans.

Usage Instructions

Tips

• For the best seal, select a lid "one size smaller" than the bowl rim.
• Ensure the bowl rim is clean and dry before applying the lid.
• When sealing halved fruit, place the cut side down on a plate then cover, or wrap the lid directly over the cut surface to minimize oxidation.
• Allow hot food to cool slightly before covering to reduce condensation and maintain texture.
• Use the mixing lid with an opening for splash-free baking or mixing.
• Use the middle lid as a grip to open stubborn jar lids.

Precautions

• Always remove the silicone lid before microwave heating; do not expose to open flame.
• Avoid using sharp objects on the lids; do not use with containers that have sharp or rough edges.
• Lids are suitable for fridge storage and general transport; not recommended for carrying liquids while shaking or inverted.
• The metal grating plates in the full set have sharp blades; handle with care and keep out of reach of children.
• Dark sauces (e.g., curry, tomato sauce) may cause minor staining to the silicone; it does not affect performance. Clean as soon as possible.
• Discontinue use if the silicone lid is torn or the bowl is cracked/deformed.

Who is this for?

• Families who frequently need to store leftover fruit, vegetables, or ingredients.
• Urban dwellers with limited cabinet space who want a modular, stackable container system.
• Cooking and baking enthusiasts who need a container that handles mixing, marinating, and storing.
• Those looking to transition away from cling film, foil, and disposable containers toward a sustainable lifestyle.
• Health-conscious individuals and parents who prioritize BPA-free, high-quality Japanese platinum silicone.
• A practical and thoughtful choice for housewarming, wedding, or eco-friendly gifts.

FAQ

Q1: Can the elastic lids cover other bowls?
A: Yes. Made from 0.5mm platinum silicone, they are highly elastic and can stretch to cover various round, square, or irregular containers, or even half a fruit. Using a lid slightly smaller than the rim provides the best seal.

Q2: Is it truly leak-proof?
A: When paired with the 3° beveled modular bowls, it is lab-tested to stay sealed for up to 14 days. Expelling air after covering is key for the best results. Reliable for daily storage; not recommended for violent shaking or inverting with liquids.

Q3: Difference between PP and TRITAN bowls?
A: PP is lightweight, durable, and economical. TRITAN is highly transparent, glass-like, impact-resistant, and crack-proof. Both are BPA-free and food-grade.

Q4: Can I use them in the microwave?
A: Yes, the bowls are microwave safe (remove the lid first). Both bowls and lids are safe for the fridge, freezer, and dishwasher.

Q5: Will the thin silicone lids tear or discolor?
A: The Japanese platinum silicone is incredibly resilient. Lab tests show it maintains elasticity and transparency even after 5,000+ uses. Avoid sharp edges to ensure longevity.

Q6: Difference between Basic and Full sets?
A: The Basic Set (8 pcs) includes bowls and lids for storage. The Full Set (14 pcs) adds professional metal grating/slicing plates for efficient food prep.

Q7: Can I mix colors?
A: Sets are pre-packaged by the factory, so each set is uniform in color; different sets can be purchased in different colors.

Q8: How is this different from standard stretch lids?
A: Standard lids are thick and often offer poor sealing. DeliOne’s 0.5mm system provides true, laboratory-tested sealing, combined with smart accessories (mixing/middle lid) and a space-saving stackable design, making it a comprehensive culinary system.
