I've had mine a while and started using it all the time recently. It's awesome! I will definitely buy more.
My climate is very humid, and even if the mandrels are dipped days or more than a week earlier, they are still good to go. No flaking. Really nice and SO smooth, more than any others I've tried, and I've tried almost all of them. Very durable and beads come off really easy. Best part - super clean holes on transparents! Oooo yeah!
I like it for the big-hole beads I'm doing now for nice clean holes. It is holding up really well, and no flaking off of these 1/4" mandrels.
