Bought a list for a DIY project. I wanted to make a chain shoulder bag out of a heavy canvas cosmetic bag, which I also bought here. As others have said, the hole punch does not work even when tapped on wood, cement, hardback books, plastic cutting boards; I ended up using nail scissors to make a hole large enough to slide through the bushing. It took some practice to get the grommets installed properly, I messed up about 3 of the 4 holes I made and they're still not perfect. Overall, it's probably not something I'll ever use again, so the poor quality doesn't bother me. This worked for what I needed with some modifications and patience.
