I found a supplier that has a color assortment, but the least you can get is 100 foot rolls of the stuff. PM me for the contact information.
I ordered 4 rolls of the stuff. Red, Black, Yellow, and Blue. The shrank thickness is 4 to 5 mils. It's close to Industry Standard I think.
The flat width is 3 1/4". I was thinking about adding this to my Ebay products. Anyone interested?
This width works for alot of popular sizes. Batteries in the picture from left to right are: A123 4S1P, 6 cell Nimh, 7.4v 2S2P 10000mah lipo, 11.1v 3S1P 4000mah lipo, and the one on the right is 7.4v 2S2P 8000mah lipo.
