Leak Proof Platinum Silicone Sealing Lid Inserts / Liners for Mason Jars (10 Pack， Wide Mouth)[Product Information]- 10 pack! These durable， 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! They also work great as a flat lid， with just a metal band / ring. Not for canning.
- Made of thick platinum cured silicone rubber， these lid inserts are dishwasher (we use the silverware area)， freezer， and microwave safe! Silicone is a safe， green， non-plastic (BPA Free) material for food use that does not leach any chemicals. Platinum cured silicone is more expensive and higher quality than regular food grade silicone.
- These liners work perfectly with metal bands， Ball plastic storage lids， or Mason Jar Lifestyle stainless steel 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.
- 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 tin flat lids， or line any type of cutout lid for candles or food.
