We have a digital Christmas light display, and I am constantly cutting, and splicing LED light strings for the props in the show. I used to order heat shrink kits with multiple sizes, and always ended up with none of size I need, and a bunch of sizes I don't need. Found this 20 foot roll of the size I used most. Price seemed good so I gave it a shot. This works great! Shrinks down well, is pliable even after shrinking. Highly recommend.
