SR1 / Spring ring

SR1
SR1

Nowadays, jewelry shop or bracelet shop can’t accurately or quickly select the proper ring size for the customer with measurement tools. And people tend shopping online, but they have no professional measurement tools to measure the finger size.The design is a portable measurement tool of spring ring size. It is based on the flexible performance. The lower part is sealed and fixed, and upper part is open. Different expansion and contraction is caused due to different finger sizes. The figure in the spring will gradually move to correspond to the lower fixed marker, confirming the final size. It is convenient and practical.
