I'm happy to tell everyone that might be wondering if they really need this tool that, if they ever buy beads, then THEY NEED THIS TOOL!
I usually buy from Aunties Beads and never need to double check them, but sometimes I grab something off of ebay and when it comes, I ALWAYS check to be sure I am getting what was advertised. Just makes me feel safer.
Also, great for making graduated necklaces. You never have a bead out of place.
A #1, if you get my drift.
