6-Piece Reusable Silicone Stretch Lids Set for Bowls, Pots & Cans (BPA-Free Food-Grade Airtight Seals in 6 Sizes)

Choose a lid size that is slightly smaller than your container’s diameter. Because the platinum silicone stretches up to 30%, a slightly smaller lid creates a taut, airtight vacuum seal. For example, use the 5.7" lid for a 6" to 7" bowl, or the 8.1" lid for 8.5" to 10.5" bowls and pots.

Yes! While circular in design, the high-elasticity platinum silicone flexibly conforms around square, rectangular, oval, and odd-shaped containers. Simply hook one corner first, then pull the opposite side tabs across to lock into place.

Absolutely. Our silicone lids are thermally stable between -40°F and 450°F (-40°C to 230°C). They can go directly from the freezer into the microwave. When microwaving, always lift one tab corner slightly to vent steam pressure. They are 100% dishwasher safe (top rack recommended).

For the tightest vacuum seal, ensure the rim of your bowl and your hands are dry. Oil or water droplets on the container’s outer edge can cause initial slippage. Once applied dry, the interior suction ridge locks firmly in place.

Both FDA and LFGB grades use 100% food-grade, BPA-free silicone. LFGB is the European standard with even stricter testing regulations for chemical extraction, while FDA is the US benchmark. Both are completely non-toxic and food-safe. All orders ship within 24 hours with tracked USPS 2–5 days delivery and are backed by our 30-day money-back guarantee.
