Delrin Ball Closure Ring | Nitrile Bead

Handmade to order in our workshop, these ball closure rings (BCRs) have a stiff nitrile bead that closes the opening without the need for tools.

A note on bead size - We can only use beads that are the same size or smaller than the internal diameter of your ring, I.E. A ring with a 10mm internal diameter can have any bead size up to 10mm but not above it

We offer some common sizes directly from our shop but are happy to provide you with other sizes if possible, Contact us to enquire.

All our Handmade PTFE & Delrin Jewellery may vary by +/- 0.2mm
