Let me start by saying I've used my fair share of copper foil tapes for stained glass projects, and this one had me both impressed and frustrated.

The Good: When working with smaller, clear glass pieces, this tape performs beautifully. The black backing gives a sleek, professional finish that really enhances the appearance of delicate projects. I found it particularly handy for intricate designs where precision matters.

The Bad: Oh boy, the thinness! This tape is like tissue paper when you're dealing with larger glass pieces. During one project, I watched in horror as it tore like wet paper while I was just trying to position it normally. Not exactly confidence-inspiring for serious crafters.

Adhesive Issues: Several users complained about the lack of stickiness, and I have to agree. The black adhesive looks great but doesn't always hold as well as you'd hope. I found myself pressing much harder than usual with the included plastic scraper to get decent adhesion.

Final Verdict: If you're doing small, delicate stained glass work and don't mind babying the tape a bit, this could work. But for larger projects or if you need reliable adhesion without constant fussing, you might want to look elsewhere despite the attractive price point.
