Hey Managep123.
I purchased the Thera P same as already mentioned. The pre-wrap is a very soft stretchable material, extremely pliable, very inexpensive, and it’s so thin that you can see through it. I wrap the shaft and then I circle the upper ball sack couple times and it stays for the day. I don’t wrap very tight at all, but I do like to get a little chubby when I first put it on - seems to make it easier to wrap.
