here is a good site that sells a ton of supplys. just search for heat shrink and it will come up with many different styles to choose from, I do a lot of shopping here for my company. Tools, screws, and just about whatever else you can think of. Shipping is usually very fast as they have wharehouse in several states. UPS ground usully arrives next day, if not 2 day max no matter where I am in the states.
I finally got the link down woo hoo.
