This set will last you a while with 275 pieces. are use this product for DC wiring in a vehicle, and I was really surprised with the quality of the product compared to similar shrink tubing I got from the automotive store. The real difference was the thickness of the rubber and the fact that there it was adhesive lined, which created a weatherproof, and essentially watertight seal, which will illuminate oxidation and corrosion, which could cause a short circuit in the future. The tubing will shrink when you heat it, and that he sieve will melt and create a very tight and strong seal. I was actually surprised with the quality of the seal. this is not an endorsement but I would highly recommend this product if you're looking for shrink tubing that only you issue percent is that a lot of the sizes are similar but the sizes are listed so you know exactly what you're getting it's just a lot of shrink tubing so it would be nice if there's a few different larger sizes, but the variety was good for the application of stranded wires, I was able to crimp the wires after sliding the shrink tubing on one end of the wires, once the wires was crimped I was able to slide the shrink tubing over the crimp and heat it up slowly with a small torch from about 5 to 6 inches away, as it shrinks after heated, the adhesive begins to melt and creates a very strong seal, I have use this product over a year ago and it's still standing strong.
