Used condition, so there are scratches on the vinyl parts, etc. It becomes less noticeable when paper is inserted. Please check the images. This is a thin type. I measured it and it was 6-7mm. *Will be shipped via Yu-Packet Post. Since there is information that it can be posted up to 4mm, I have listed it as a set of 10. In the unlikely event that it cannot be posted, the order will be cancelled. Please purchase only if you agree to this.
