PandaHall 30pcs 5 Colors Brass Ring Blanks Pad Rectangle Ring Pad Adjustable Finger Ring Base for Embellishment Jewelry Making

Product came as pictured. High quality as far as strength goes. Unsure if metal oxidizes and stains fingers yet, so far so good after three days.I got these to glue flat back stones/cabochans onto. Adjustable, nice variety of colors. Recommend for cocktail ring making.

I love these rings so far! They look sturdy and I look forward to creating nice jewelry pieces with these rings.
