Yamato-ya Safety Chair Belt YC-01 Thank you for viewing! This is a belt for use with Yamato-ya's Sukusuku Chair series, a high chair. I used it for about a month with the Sukusuku Chair Plus. There are no noticeable stains, scratches, or odors, but there are fine scratches on the buckle. Please check the condition in the photos before purchasing as this is a used item. It has been lightly cleaned with a disinfectant wipe. No box or instruction manual. The instruction manual can be found by searching for the product number on the internet.
