Review: Nice and thick strong they shrink perfectly! - 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!
Review: Great heat shrink and has adhesive layer - 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.

### ⭐⭐⭐⭐⭐ Fantastic value and works great
*by T***S on October 22, 2025*

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.
