YKK Efron zippers 33 pieces, 18cm each. Colors: Purple, Blue, and Gray. Please check the photos for the color variations. One type of zipper (3 pieces) is different (see photo 7). Also, there are some areas that appear whitish (see photo 8). Although these are unused items, please understand that they have been stored at home. The opening and closing function works fine, but they have been stored for a long time, so I hope those who understand this will consider purchasing them. *If you are considering purchasing multiple items, they can be combined for shipping, so please inquire before purchasing. *If you would like 15 or more, please let me know your desired zipper type, quantity, colors, etc., and I will create a dedicated listing for you, which will take a little time. Shipping is closed on Saturdays, Sundays, and holidays. #YKK #Zipper #Assortment #Handmade #Sewing #SewingMachine #Handmade #Zipper #Long #Long #Bulk #EfronZipper
