I tried using a few, but I couldn't do it well, so I'm putting them up for sale. I couldn't do it well with the eyelet punch. (It may be because I have a chronic illness in my dominant hand and my grip strength is weak...) One side (100 sets) is unopened, and the other side has been used for testing, so the number is different. I purchased a set of 200. Some washers are stuck together. I counted them, but since the washers are stuck together, I apologize if the count is off. Color: Gold Material: Unknown Purchased from Rakuten D7 Parts Beads Craft Materials. "Ha 5" Please refrain from purchasing if you are nervous about home storage. Please also read my profile.
