Useful to have, but hard to find. This is a product for kimono dressing. These are S-shaped pins that can secure the collar of a men's kimono. Secure the collar for a crisp, clean look at any time. Use them by inserting them between the seams of the upper and lower collar at your preferred collar position. They can also be used on the collar of a nagajuban (undershirt), making them convenient for women who are active, such as in dance. Please note that this product is designed to match traditional hand-sewn construction, so it may not be usable if the collar is machine-stitched with fine stitches. Comes in a resin case. *This text is partially quoted from the packaging.
