Thank you for viewing. This is a Plarail snap button. It's a type that can be easily attached by hand, without any tools. I am selling these to organize my sewing supplies. I purchased them about 6 years ago, but they have been stored unused. Although unopened, the cellophane tape that seals the back of the package has peeled off due to deterioration. [Product Condition] New, Unused Although unopened and unused, they have been stored at home, so please consider this before purchasing. #Plarail #SnapButton #Hook #HookButton #PointRedemption Inagaki Fuku-shoku Snap Button Plarail, 6 sets, TSB002
