Product Introduction


From Amazon
This earring back was developed with inspiration from the structure of a mechanical pencil, and has a completely different mechanism from previous earring backs. Since it will not come off unless you pull the knob, you will no longer have to worry about losing your precious earrings.
The material used is surgical stainless steel, which is used for surgical tools and bolts that are inserted into the body when a bone is broken. It is said to be sturdy, unbreakable, and less likely to cause allergic reactions (*This does not mean that it will not cause allergic reactions in all people).
The thickness of the earring post (the rod part) varies depending on the earring, ranging from 0.7mm to 0.9mm. Earring locks are compatible with earring posts ranging from 0.6mm to 1.1mm. One pair can be used with almost all stud-type earrings.

From the Developer
Pierce locks are made by combining the technology of factories in Nagano Prefecture. There are nine parts in a product of about 5 mm. Each part is manufactured in a specialized factory with a precision that does not allow for a deviation of 0.01 mm, and the final assembly is done by hand.
Due to the precision required, we cannot mass-produce them, but we make each one with care, so that as many people as possible can continue to enjoy fashion with peace of mind.
