Wedding Ring Stretcher ans Sizer – Niessing

This innovative tool, originally developed by Niessing in the 1920s, forms the technical foundation for a device that is still manufactured today due to its simplicity and reliable functionality. It uses the proven spindle-press principle to expand and reduce rings with precision. The large ball-shaped handle allows effortless adjustment of ring sizes with minimal physical force.

For smooth and safe operation, it is important to use seamless rings without gemstones, made from high-quality alloys.
