The BERGEON Ring Mandrel – Black Teflon is a precision measuring tool designed for accurate ring size measurement and jewellery workshop applications. Made from high-quality Teflon, it provides a smooth, non-scratch surface that protects delicate rings during measuring and fitting.
The low-friction surface allows rings to slide smoothly along the mandrel without damaging precious metals or gemstones. This makes it ideal for goldsmiths, jewellers, and jewellery repair professionals who require precise measurements while preserving the integrity of the jewellery piece.
Thanks to its durable and easy-to-clean material, the BERGEON Teflon ring mandrel offers long service life and reliable performance in professional workshop environments.
