Review on XHF 205 PCS 3.5" 3:1 Adhesive-Lined Heat Shrink Tubing Kit For Auto And Marine Applications by Robert Morrison

I used this to secure knots on some cord. It is so clear it is difficult to see it on the picture.This also works for labeling things. Print out a tiny tag, put it around the cable or wire, then shrink some of this around it. You can easily read through this and the label will never come off.
