Keep those cells safe! These ring insulators are made of adhesive cardboard paper, and come in four colors: black, green, red, or white. They are easier to use outside of heat shrink, but can also be used inside, and are an easy peel-and-stick. Pair them with our selection of heat shrink to customize your pack.
Note: Colors may be slightly different than those shown in the photos. The green is a darker tint, and may appear to be black in the photos.
