Metal screw-in hit points. For when they come off or need replacing. Also suitable for the scissors I am selling here. They make a clicking sound like old-fashioned scissors. There are two types of screw standards, and almost all domestic scissors use one of these two types. In JIS standards, these are metric coarse thread screws, with two sizes: 2.5mm and 3.0mm. Since it's often difficult to know the size, I will basically send a mix of one of each. If you want two of either 2.5mm or 3mm, please comment. Size notation: ・M2.6×P0.45 ・M3.0×P0.5 Material: stainless steel 【How to Replace】 Since they are screw-in type, you can easily replace them by turning the screws. In rare cases, they may be attached with adhesive, so be careful not to break the screws with pliers when replacing them. ※ Depending on the product, you may need to adjust the height of the handle. I am selling sets of 6 and 10 separately. If you want a large quantity, please comment. Up to 30 pieces are available. Shipping is not available on Mondays, which are regular holidays. Shipping will be by standard mail. For Mercari mail tracking and anonymous shipping, it will be an additional 140 yen, so please comment.
