Ultra-compact size-0 snaps in a 6 mm diameter for barely there closures on fine or dark fabrics. The black finish helps the hardware disappear while providing rust-resistant durability. With twelve complete sets on each card, you have plenty for doll clothes, lingerie, and trims. Sew with small, even stitches through the mounting holes to maintain a smooth profile and reduce strain on delicate fabric layers during use and laundering in regular garment care cycles.
