This stuff is awesome! I make/sell covers for binders and need to mail them rolled up so they don't get any creases in them. I was putting them in brown mailing tubes but I wanted an extra layer of protection during mailing. I also send some small papers and things with my binder covers and I wanted all of the items I was mailing to be contained. I purchased these along with the heat press machine and it gives my products such a professional look.This is a TON of tubing though. I will probably have this thing for 5 years even with the thousands of packages I ship. The thickness is very nice. I have no worry that these will get a hole in them. Very pleased with this product.
