Flat back round cabochon beads, suitable for gluing into bezel settings, onto flat back bails, even directly on to fabric.
There are many suitable adhesives - one that we recommend is E6000.
Cabochon beads have a flat back and are not drilled. These are a classic circular shape with a smooth surface and they are a standard size that fits many styles of setting, both vintage and modern.
Please check dimensions to make sure they will fit your project.
