Regular price $69.99

Your favorite ring is now too tight to wear? You can enlarge the ring size with precision!

Try the Ring Size Enlarger Mandrel. You don't have to take the ring to the jewelry repair shop - expand it yourself! 

SOLID & EFFECTIVE EXPANSION SYSTEM - We offer a simple but highly functional set of ring resizing tools. You'll receive a metal alloy ring mandrel and tapered expander tool - this is used as a plunger inserted into the mandrel. A wear-resistant mandrel base offers protection to your work surface. The ring mandrel is a multi-stage collet with ring size tiers ranging from 16.7 to 26 mm. 

EASY DIY RING ENLARGEMENT - Anyone can perform ring size amplification using this toolset. To achieve DIY ring resizing, start by attaching the mandrel base to the bottom of the mandrel. Slip the ring into the mandrel and keep the tool standing upright. Insert the expander tool into the mandrel cavity. Use a small hammer to force the expander down like a plunger. Proceed slowly to avoid damaging the ring. Once the ring fits smoothly into the desired size tier, you are done. The ring is resized! 

SPECIALLY DESIGNED FOR METAL RING ADJUSTMENT - Our ring mandrel kit is engineered to work on gold, silver, copper and platinum rings. It is not meant to be used on rings set with stones. Please do not try to resize those types of ring with this tool. But for rings of the right type, using this ring expander device can save you jewelry repair costs.
