Comes in a full sheet so you can make the seal the shape you need.

I aswed it to cut out a gasket for my electrical junction for the house. It worked very well. The idea was to make sure water does not go into the conduit leading inside the house.

This food-grade silicone was perfect for cutting a small circle to put into the lid of a bottle that originally came with a foam insert. I traced the lid and cut just inside the lines. The width is perfect and just about the same as the original foam piece. It was easy to cut, wash, and has made the bottle leak-proof once again! I would definitely purchase again.

Creating artwork on large glass canisters and needed odd sized sealing rings. This product is perfect!

After searching for weeks for the right size seal for small jars. I used this silicone sheet to cut the size seals that were needed. A great value for the money.

This Silicone Sheet, 1/8" thick, worked perfectly to make a new sealing gasket for my antique pressure cooker. The Presto Model 304 stainless steel copper bottom pressure cooker is the best pot ever made and the sealing gaskets are no longer available. The food grade silicone sheet was easy to cut and I was able to replace the old, dry, shrunken gasket to allow many more years of use - I hope!

Exactly what I was needing. Will be ordering more in the future. If you buy the red lid 1.3 gallon carboys online for making mead and wine and lose the liner/gasket that is included under the lid this is literally the perfect material to replace it.

Lets be clear not 3 sheets only one but it is silicone
