Great product, the batch I got seemed to be old and had lost it's stickiness
I absolutely love this product and use these all the time. I ordered both the 3/8 inch and 1/2 inch packs, and for some reason the 1/2 inch pack seemed old or something, as it had lost a lot of stickiness on the side that is attached to the large backing sheet. The other side, which has individual plastic covering, seemed fine. Hopefully just a bad batch, I will order again and see what I get.
