I only used the longest one which is the "enlarger", and it worked great. I wasn't sure if I would be able to enlarge a hole as some said it was just to clean out the holes and get rid of any materials that were inside etc. But I had some ceramic (or glass) beads that wouldn't fit onto a rod I was using for a garden stake, and I was able to enlarge the hole enough to make them fit. I only enlarged it probably a milemeter, but that was all I needed. I assume I could have made it bigger. I guess it would be nice if the handle was bigger, but this seems to be standard.

These are marvelous reamers, both useful for small bead's and the larger one's. Very happy with my purchase 😊

Llegó en perfecto estado y son muy útiles para lo que lo necesito.

Les manches de 2 outils utilisés n'ont pas tenu plus d'une minute. Sans le manche, il est plus difficile de tenir l'outil d'une main et la perle de l'autre mais j'ai réussi malgré tout à agrandir le trou des perles, ce qui explique les 3 étoiles.

This arrived well ahead of schedule. Very pleased! Product is as described and works very well.
