"This roller works very well. It will leave lines on your bead, but that's not a big deal for me. I really love that the 2 halves fit together so well. I have 2 bead rollers from a different seller, and they both work just fine, but there is a looseness in the sliding grooves, they kinda wiggle and it bothers me. This one fits perfectly together which makes rolling the beads a whole lot nicer."
