18pcs Stainless Steel Grooved Finger Ring for Jewelry Making,7/8/9/10/11/12 Ring Core Blanks 8mm Wide Round Grooved Inlay Rings for Men Women DIY Crafts(Black)

Quality product

Plenty assortment for the ring making hobbyist.

Love how they are easy to use and looks great filled with resin.

Low quality to my standards, but great for practice and throw aways.

Got these for kids and grandkids to make their own rings using UV resin and mica powder. Quick and attractive results that everyone liked. Several of them wear them daily.

Easy to work with, wish they had the size stamped inside of them instead of on the bag

I think the black coating will be problem, at least with the process that I follow in making inlay rings. There's a lot of sanding and filing involved shaping the inlay material with the ring and I can't see how the finish on these will withstand that process without marring. Admittedly I have not tried that because I would risk having the remainder of the pieces that I would have limited use for, if at all. I have this reseller stainless steel version of the product and love it. I've made several rings using those versions with no issues, what I'm worried about this black finish.....

Quality very good. Will buy again.
