Fine Silver Bezel Cup 4mm plain round. Price is for 1 bezel cup.
The best way to use these is to have two thicknesses of metal clay, one on
top of the other. On one layer of metal clay use your bezel cup (upside
down) to push down and remove this part (just like using a cutter). Place
the two pieces of metal clay together using paste and then place your bezel
cup in to the removed area (sitting up the correct way). This way you will
get a perfect fit.
