Heavy‑duty size‑7 snaps designed for thick layers and high‑stress points. The 15 mm diameter spreads load widely, helping closures stay aligned on coats, costumes, and sturdy bags. Nickel finish coordinates with common metal trims and provides a durable surface for repeated opening and closing. Four sets per card are ideal for key placements such as jacket plackets, strap tabs, and pocket flaps where reliable, low‑profile hardware is preferred over bulky buttons or buckles.
