This is a repair and temporary fix kit for broken zippers. Includes 2 each of S/M/L sizes, for a total of 6 pieces. This is a zipper slider that clamps on and is secured with a screw. 【Important Notes】 This product does not work with all zippers. It may not be compatible depending on the zipper you are using. When I tested this product, it didn't work on thin zippers like those found on pouches, but it did work on the zipper of a zip-up hoodie (see image 6). Sometimes it worked after adjusting the size or direction of the zipper slider, or after reattaching it several times, but I cannot determine which zippers this product will or will not work with. Please note that we do not accept returns, refunds, or complaints if the product does not work with your zipper. Please be aware that the hole for the slider pull cord may be small. If the hole is too small to pass the cord through, you can enlarge it with a thin screwdriver or similar tool. ----- If you prefer an anonymous and trackable shipping method, you can change the shipping method for the following additional fees: ・ Yu-packet Post mini shipping: +100 yen ・ Yu-packet Post shipping: +130 yen If you would like to change the shipping method, please comment before purchasing. ----- ◆◆◆ We will discount the difference in shipping costs for combined shipping.
