These pads can be used as non-slip grips or cushions for opening and closing doors. They are approximately 9mm in diameter. I believe they have been opened to check the contents, but they have not been used. Please understand that these are items stored at home and are therefore used. I would appreciate it if you could purchase them if you understand this. *To avoid any problems, we do not offer individual price reductions. We review prices regularly. We apologize to those in a hurry m(_ _)m Instant purchase is welcome. Please consult us for bulk purchases.
