The key of the 100 yen locker around 30 years ago has gone away from rust. Although there was a person who put a 100 yen coin, I could not use it because the key naturally does not turn. There is a request for repair (although I am a completely amateur) The result I searched for is this product. ◎ design: small, thin and cool ◎ functionality: easy to turn ◎ price: too cheap! It is! But no problem at all Overall rating: CP is the best! Only one rotation direction is right, so it is best if there is left specification.
