Thank you for viewing. I am selling these coasters because I have stopped collecting them. There are four unopened items. If you purchase multiple items, I will adjust the price, so please comment. This price is per item. This is a cover to protect round coasters with a diameter of 90mm, with holes for attaching ball chains at the top and bottom. Simply insert the coaster into the slit on the back and cover it with the lid for easy installation. -------------------------------------------------- [Contents] 3 sheets / Ball chain x 1 [Compatible Size] Approximately 90mm in diameter [Color] Clear [Materials] Outer packaging/PP, Cardboard/paper, Main body/Cover: PVC, Ball chain: Brass [JAN code] 4589901890157 --------------------------------------------------
