650pcs Heat Shrink Tubing Black innhom Heat Shrink Tube Wire Shrink Wrap UL Approved Ratio 2:1 Electrical Cable Wire Kit Set Long Lasting Insulation Protection, Safe and Easy, Eco-Friendly Material

These work great, they are plenty long and there are a ton of different sizes. They only problem I have is that there are so many of them that it stretches the plastic case they come in.

These heat shrink tubes are excellent. They come in a wide variety of sizes, and I had no trouble using them on the wires I intended to splice. Although I’m not particularly skilled at soldering, I left some sharp edges, but the tubes didn’t break when they were shrunk. This assurance in the product’s quality gave me great confidence. I used a lighter to shrink them, and fortunately, they didn’t catch fire. For my initial use, I needed the smallest size available, and it shrunk perfectly. Overall, I believe this was a wise purchase, and I anticipate getting a lot of value out of it.

This set was such a great value! Every one is black, but has numbers to say what gauge it is. So easy to use. Have not melted one yet. Fantastic buy, will buy again.

Works great

So good. Bought this kit for a stereo install for my car. Now I have enough of this to do 100 more...lol. I think I went overkill on the size of this kit, but you never know what else you'll need this stuff for. I ended up not really needing it to be honest, but I kept it anyways. I found out that another company made perfect plug and play wire harness kits for the stereo installed into my car. All I needed then was that black Tessa cloth type tape to wrap it all in for a professional OEM type look. Think I used one or two pieces to keep a few wire looms together and out of the way/protected. These do what they need to do and react to heat well.

Many sizes and shrinkage results are good when using a heat gun. Appearance is also good.

I love that it has all kinds of sizes for all kinds of projects.

Product did what was to do the shrinkage and durability was very good
