Wirefy 1" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll

This heat shrink tubing has become a staple in our household. Originally bought for my husband’s electrical work, it’s now found a place in my craft projects too. It’s easy to use—just slide it on, apply heat, and it seals perfectly, even keeping water out.The quality is solid, with good heat resistance and strong adhesive properties. It holds up well in tough environments and offers great value for the price. You can cut it to the length you need, which is super convenient.That said, some tubing diameters don’t quite match the listed specs, and opinions on thickness vary. But overall, it’s a reliable, multi-use product we keep coming back to.
