This sterling silver extension chain is 7.5 cm long, 3 mm wide, and has a clasp on one end. It would be a perfect addition to a bracelet or necklace in order to increase the size up to 3" inches. Look also for the other similar extensions.
This and 75% of my inventory is on sale and on clearance. There are no returns on this item. Please make sure you look and the size and compare it on a ruler. Many items under $20 are small and maybe even tiny. I have a large number of customers that specifically looks for these tiny and small charms and earrings.
