DECYOOL Locking Metal Pin Backs — 100 Pieces, Nickel-Plated Spring-Loaded Low-Profile

DECYOOL locking pin backs are nickel-plated metal retainers that snap shut to keep enamel pins, badges, and brooches firmly in place.

These 100-piece locking pin back set replaces flimsy rubber or butterfly clutches with a spring-loaded, low-profile clasp made from nickel-plated copper. Each keeper is 0.39" (1 cm) in diameter and 0.24" (0.6 cm) tall, designed to stay discreet behind your pins while providing a secure hold on jackets, hats, bags, lanyards, and uniforms.

How do DECYOOL pin backs keep my pins from falling off?

The locking mechanism uses a spring-loaded fastener that snaps onto the pin post and resists accidental pulls. To remove, simply pull the base away from the post; no tools or tiny wrenches are required. Compared with rubber clutches, these metal keepers provide a firmer grip and better long-term durability.

• Spring-loaded locking action for secure attachment
• Pull-to-release base for quick removal without tools
• Stronger hold than standard rubber or butterfly clutches
• Rust-resistant nickel plating for extended use

Will these pin backs fit my enamel pins or badges?

Yes—each DECYOOL locking pin back is sized to fit standard pin posts commonly used on enamel lapel pins, brooches, insignia, and name tags. The compact 1 cm diameter and low-profile height let them sit flat against fabric without poking skin or creating bulk. They pair well with most 0.8–1.2 mm post thicknesses used industry-wide.

• 0.39" (1 cm) diameter, low-profile 0.24" (0.6 cm) height
• Compatible with standard enamel pin posts and badge pins
• Lightweight design keeps pins balanced and discreet
• Works on jackets, hats, lanyards, bags, and uniforms

Are these pin backs durable for everyday wear?

Made from nickel-plated copper, DECYOOL pin backs resist corrosion and stand up to daily use better than plastic or soft rubber alternatives. The smooth, flat back reduces friction against clothing and helps avoid scratches on skin. Their sturdiness makes them a reliable option for collectors, service uniforms, or frequent pin wearers.

• Nickel-plated copper construction for rust resistance
• Smooth flat backside prevents fabric snags and skin irritation
• Heavy-duty spring gives long-lasting retention
• Bulk pack ensures replacements are always available
