This is a set of three boxes of single-sided eyelets (new, unused) and a bulk sale of eyelets only (without washers). I used these for handmade crafts, but I ended up buying too many, so I'm offering them to anyone who needs them. Size: Outer diameter 12mm, Inner diameter 7mm Model Number: #20 Brand: SUN11-165 SUN11-166 SUN11-167 Colors: Nickel (Silver) Black Nickel Gold
