### ⭐⭐⭐⭐⭐ Good tape for neat wrapping.
*by J***. on May 18, 2025*

This is heat shrink tape which I used to deal with loose ends on a wrapping project. It shrinks when hit with a heat gun, and secured my loose ends.The final product looks smooth, and you need to really search to find where the end is. This is a good material for securing loose ends on round materials.

### ⭐⭐⭐⭐⭐ Good fit
