Thank you for viewing. This is an aftermarket boot zipper with 8 holes. As shown in the example photo, threading the laces allows you to put on and take off your shoes by zipping and unzipping the zipper. This product is perfect for those who find it troublesome to take their boots on and off, or who want to speed up the process. ☆ The zipper has an auto-lock mechanism, so it won't easily come down. ※ If you use boots for work or mountain climbing, it is recommended to tie the laces tightly to ensure the shoes function properly, so it is best to avoid using this product. Please note that this product is not suitable for those who use boots as tools. ※ Please use this product only as part of your fashion or as an aid to putting on and taking off your boots. The following is a description of the product. From cutting to processing, assembly, and sewing, everything was done by hand. The size is 18 cm long and 7.5 cm wide. The distance between the holes is 20 mm. The materials used are: Black smooth cowhide Black smooth cowhide for the lining Black YKK zippers Silver eyelets Black thread ☆ Custom orders on Mercari are no longer available. ※ If you would like to commission a piece, please see the page currently listed on another handmade service.
