Please look at the 58-022 and the taller 58-126. These both have what's called a "fin seal" that runs down the middle of the pile. I think one of these should work as a replacement for you bubble, which I wasn't able to find. Take a look and see what you think. You can order a sample of each here, that way you can try them out before you commit to a purchase. |
