Purchased from a chain shop in Okachimachi. Made in Japan, produced in a domestic factory. The screw chain is designed to twist in a spiral, just like a spiral staircase. It's a delicate size for women, but men can also wear it for a stylish, understated look. The opening of the round clasp, which is the most easily broken part, is also welded for peace of mind.
