Three clips to secure the Date eri (collar). I changed the quantity from two to three. I used them once and left them clipped to the Date eri, so the middle one is slightly raised. That's how they're used, so there's no problem with their use. Express delivery is available for an additional 300 yen, and orders will be accepted until the 7th. However, delivery after that date is not guaranteed, so please be aware of this before purchasing.
