They are created from 21 gauge square Black wire which is made in the USA. They measure 37mm X 20mm. The ends are deburred so they will be smooth and comfortable to insert.
Since 21 gauge square wire has 30% more volume than 21 gauge round wire, these are a "standard" ear wire hole size.
21 gauge = .724mm on each side
