This range of heat shrink tubing offers excellent value for money. It fits perfectly 2:1 as advertised. Different sizes and colors are useful. The case is made of durable, soft plastic, not a brittle, transparent material that breaks easily. The dividers inside the case are not removable, they will not fall out or come loose. I prefer the plastic cases with removable inserts. NTE also makes these kits with all red or all black tubing in a variety of sizes. Here is a complete black set: NTE 2:1 Heat Shrink Tubing Black Mixed Sizes 2-1/2 158 pc box Sorry I couldn't find a complete red set on Revain at the moment.
