Leak Proof Platinum Silicone Sealing Lid Inserts/Liners for Mason Jars (10 Pack, Wide Mouth)
*10 pack! These Reusable Silicone Discs Make *Wide Mouth* (3" internal diameter) Ball plastic storage caps, Mason Jar Lifestyle stainless steel storage lids, and some other lids both leak proof and food safe!
*Safest Material - Platinum cured silicone is more expensive and higher quality than peroxide cured silicone. Silicone rubber is a BPA free, non-plastic material for food use that does not leach any chemicals. Meets FDA and LFGB (European) standards.
*Easy to Clean and Use - Dishwasher, freezer, and microwave safe! Now with a small tab to make them easier to remove.
*Multi Purpose - Work perfectly with metal bands, Ball plastic storage caps, Mason Jar Lifestyle stainless steel storage lids, and MJL plastic storage lids. Because silicone is a flexible material, they fit some other lids too (but not perfectly). If they seem a little too big for your lid, you can trim them with a scissors.
*Many Uses - Perfect for storing anything in the pantry, fridge, or freezer. Prevent food contact with plastic or tin, line a straw hole lid for transport, replace your rusted metal flat lids, or line any type of cutout lid for candles or food. Not for canning.
When I decided to invent this product, I was trying to solve two common problems with Mason jar lids: either they leak (like the plastic Ball lids), or they are not food safe (like many decorative lids). These discs solve both problems! The food only comes in contact with the silicone, and it makes many lids airtight and watertight.
We have added a small tab to one side to make them easier to remove. When used with a solid lid, the tab should stick down. When used with a band only, the tab should stick up.
They are made of 3.3mm thick, clear, food grade platinum cured silicone rubber.
Glass and platinum cured silicone are 2 of the safest materials available for food contact!
