コ レ ク シ ョ ン: tie pin

Men's tie clip, slide bar collection.

Tie pins are used to keep the tie out of the way when bowing or eating.
Clip the pin to the tie, thread the chain and slide bar through the buttonhole, and button it up to keep the tie from coming down in front of your face.

Originally, it is an accessory for men, but it is also fashionable for women.
