The "eri-shin" is inserted into the collar of the Nagajuban* to create a clean, rounded appearance at the back of the neck. It is also used in the same way for yukata. This is  exclusively used for women's kimono and yukata.

*A Nagajuban is an undergarment worn beneath a kimono, similar to a shirt worn under a suit.
