This is a bib clip given away by Chuo Shuppan, and is not for sale. It allows you to easily turn a handkerchief or other cloth into a bib or apron just by clipping it on. It can also be used as a hat clip. The length of the strap is adjustable, so it can be used until your child is quite big. Although it is unused, it has been stored for a long time, so I've listed it as "like new." Please understand this before purchasing.
