Thank you for viewing. This is the official mook book for mt, a masking tape brand released in 2017. I bought it at a bookstore and kept it sealed, as I didn't want to open it. I will send it to you unopened, so please be aware that I cannot confirm the deterioration of the special appendix tapes. There are no noticeable stains or scratches, but this is a personal inspection. For those who understand that this is a used item. Please refrain from purchasing if you are concerned about minor details.
