TKDMR 446 Pcs Heat Shrink Tubing Kit - 4:1 Ratio Adhesive Lined, Marine Grade Shrink Wrap - Industrial Heat Shrink Tubing,Black

These shrink tubing pieces are amazing. They work very good. They shrink up quite a bit. They’re thick strong. I am very happy. I bought them if you’re looking for good quality string tube this is worth every dollar! I went through a bunch of crappy cheaper ones way thinner than they don’t have as good as protection these blow them away!

Great product. Love the sizes of the tubes and it's shrinking capacity. This product has been the best heat shrink that I have used, much better than what is available in electrical aisle of stores in the city. Needs more heat to shrink the tube in comparison to typical heat shrink.

These work really well, unlike some which don't shrink very much, or don't ooze the adhesive (Because they cheaped out on it) these actually do a decent shrink job and do ooze out the adhesive a bit so I know I got enough of a squeeze. The amount of them is great for the price, and although I usually buy it by the roll, having them pre-cut does save some time if you're doing a lot of them. The case is like most other ones - lousy. If it drops, it will probably break, or unhinge itself. I'd wrap a thick rubber band around it if you are worried about the latches not really staying latched. That being said, I buy these for the heat shrink wrapping and not for the case, hence the 5 stars.

I don’t usually take the time to write reviews, but this product really impressed me. From the moment I opened the box, I could tell it was made with attention to detail. The packaging was clean and protective, and everything inside arrived exactly as described. The build quality feels solid and durable — definitely not one of those cheap, flimsy versions you sometimes get online. After using it for a while, I’ve noticed a real difference in performance and consistency. It does exactly what it claims to do, and in some ways even exceeds expectations. The design is practical, intuitive, and easy to use, even if you’re not particularly tech-savvy (or handy). I also appreciate that the instructions were clear and simple to follow. Another bonus: the customer service seems responsive and genuinely helpful, which is rare these days. Overall, I’m very happy with this purchase and would absolutely recommend it to anyone on the fence. Whether you’re buying it for yourself or as a gift, it’s well worth the money. I’d definitely buy from this brand again.

Product is thicker walled and shrinks well. Good price.

Nice variety of sizes. Have not used it yet on wire connections, but I did use it to fix my glasses when one of the temples broke. Used two different size tubes. Worked great. You can use them for more than just wires.
