The core PP tape and D-rings are made in Japan, and the plastic parts (buckles & adjusters) are from YKK. We use a thick, 100% cotton canvas fabric. The white parts are not pure white, but rather an off-white color. Width: 2.5 cm Collar size: Approximately 33-48 cm Before use, always check for any damage. If there is any damage, please do not use the collar and replace it with a new one. These are handmade items, so the stitching may not be perfect, and there may be slight imperfections. We appreciate your understanding and ask that you only purchase if you agree. Please note that we are not responsible for any accidents or troubles that may occur during use. Shipping will be via non-standard mail, so there is no guarantee, and it will be delivered to your mailbox. If shipping from a post box, we will send you a "shipping confirmation email" when the item is dropped off in the post box, regardless of whether there is a collection on weekends or holidays.
