Review on Enhanced Shrink Tubing Tubes: KOOWIN Ratio for Optimum Results by Jeff Sorensen

I am a retired engineer and used to work in measurement and control technology for a large automobile company. Heat shrink tubing is used for professional electrical connections and the insulation of these connections. This kit contains the most commonly used sizes of red and black heat shrink tubing. The plastic case is very convenient for sorting different sizes and avoids mixing. The lid has latches to keep the case closed to keep the contents inside the case. This is a very convenient way to store heat shrink tubing.
