That thing on binders. Haven't you ever noticed the non-slip rubber pads disappear? I saw a question on Yahoo! Chiebukuro asking "Where can I buy these?" so I listed them and someone bought them, so I'm selling them again! * For repairing or replacing binder pads * As a spare when you lose the original parts * To prevent documents from slipping and reduce stress 【Condition】Brand new, unused 【Shipping】Will be shipped via standard mail with measures to prevent water damage. - Color: Black Thank you for looking.
