Glossary

Plain-English definitions of the custom-pin and merchandise terms buyers see in our quotes and emails.

A – D

AQL 2.5
Acceptable Quality Limit per ISO 2859-1. Our standard inspection level — statistically rigorous sampling rejects batches with too many defects.
Antique finish
Plating that mimics aged metal: antique gold, antique brass, antique silver. Achieved by oxidizing the plated layer then partially polishing high-points.
Butterfly clutch
The standard pin back: two flexible metal wings that squeeze a pin post. Cheap, secure, replaceable.
CMYK Offset
Four-color process printing on button badges, paper cards, and the substrate under epoxy domes. Photo-realistic.
Cloisonne
Premium enamel work where colored enamel fills metal compartments (cloisons), then is ground flush. Jewelry-grade durability.
Die-struck
Pin or charm stamped from a steel die without enamel filling — pure recessed/raised metal relief. Heritage aesthetic.
DDP
Delivered Duty Paid. We handle export docs, shipping, customs and last-mile delivery. The simplest Incoterm for buyers.

E – M

Enamel (soft)
Color paste filled into metal channels and baked. Surface is slightly below metal lines — you can feel the texture. Most common pin type.
Enamel (hard)
Same process as soft but baked, refilled, baked again, then polished flush to a glossy mirror surface. Premium feel.
Epoxy dome
Crystal-clear resin coat over a flat printed surface. Adds depth, gloss and scratch resistance. Used on button badges, acrylic charms, photo magnets.
FOB
Free On Board. We get the goods to a Chinese seaport; you arrange shipping. Cheapest at unit level but you handle logistics.
Hangtag card
The cardboard backing card pinned through a packaged pin. Carries branding, barcode, and gift-message space.
MOQ
Minimum Order Quantity. Our standard is 100 pcs per design; some products (PVC keychains, button badges) require 200-300.
Magnetic clutch
Replaces butterfly clutch with two rare-earth magnets — attaches without piercing fabric. Premium feel, ~$0.40 extra per pin.

N – Z

Nickel-free
Plating without nickel undercoat — required for EU markets and skin-contact products. Adds 5-10% cost.
ODM
Original Design Manufacturing. We design from your brief; you own the artwork. Best for resellers without an in-house design team.
OEM
Original Equipment Manufacturing. You provide design; we manufacture. Standard for brand owners.
Pantone Coated
The Pantone color standard for printed and coated materials — what we match our enamel and print colors against.
Plating
Electrochemical deposition of a thin metal layer over the base metal. We offer 12+ finishes: gold, silver, rose-gold, antique-brass, gunmetal, copper, nickel, chrome, dyed-black, rainbow, two-tone, and custom.
REACH
EU regulation on chemical safety. Heavy-metal release tested in third-party labs; certificate included with EU-bound shipments.
Rubber clutch
Soft rubber alternative to butterfly clutch. Easier to grip with arthritic hands; preferred by senior-citizen recipients.
Safety-pin back
The traditional button-badge mechanism — a sprung steel pin attached to the back. Cheap, immediate, no separate clutch needed.
Sample fee
$30-80 charge for a pre-production physical sample. Refunded against your bulk order.
SMETA
Sedex Members Ethical Trade Audit, 4-Pillar version covers labour, health-and-safety, environment, business ethics. We pass annually.
Tooling fee
One-time charge for cutting your custom steel die or 3D mold. $80-200; waived above 1,000 pcs.
