Thank you for viewing. All YKK brand. ⚫︎ Approximately 17cm zippers, 77 pieces ⚫︎ Extras: 4 pieces with stains are included. (See photo 3) Although new and unused, these items have been stored at home for a long time. As I am a non-professional, there may be other stains. I've included items that I noticed as extras. Thank you for your understanding. These items are from my mother, who used to do dressmaking, so I will need to confirm any questions with her before responding. Special price for bulk purchase. No price reduction. No individual sales. Thank you. Pocket zippers Bag zippers Handbag zippers Handmade supplies Handmade materials Handmade
