Large, black size‑7 snaps for dark garments and utility projects. The 15 mm scale delivers reliable holding power on outerwear, costumes, and heavy accessories while keeping a clean, low‑profile look. The rust‑resistant finish stands up to regular use. Each card supplies four complete sets for strategic placements at plackets and tabs where durability matters and discreet hardware is preferred over bulky closures that might distract from design lines or add weight.
