A very pretty crimp bead at first look but you have to treat them with kitten strength when you squash them with a crimping pliers. You have maximum two squashes before it crumbles. These are fine if you just squash them flat, once, with a flat nose pliers. But if you use a crimping pliers, save yourself the aggravation and get something else. I wish I could return the ten units I bought but I have used a few to then find out that they are worthless for me.
