Every sewing kit needs a good stash of snap fasteners, and this set gives you a ton – 100 sets total! That's 50 black and 50 silver snaps, all in the 10mm size (about 3/8 inch). They're made from solid copper with a nice smooth finish, so they're strong, won't rust easily, and can handle machine washing. Each \set\ includes the male and female parts that snap together. You sew them onto your fabric – they're perfect for replacing lost snaps on baby clothes, jackets, jeans, shirts, or for adding closures to DIY projects like bags, costumes, or accessories. They give a clean, invisible closure when done right. Just remember you need to sew these on; they're not the hammer-on or press-on type. Great for crafters, tailors, or anyone who does quick mends at home. A super useful and economical sewing supply to have on hand.
