Is This Enamel Pin Durable for Everyday Use?
Yes. This hard enamel pin is manufactured using a professional cloisonné process. Molten glass enamel is baked into recessed metal cells at high temperature, then ground flat and polished — resulting in a smooth, glass-hard surface that resists scratching, chipping, and color fading. The gold-toned metal borders are electroplated and sealed, providing a durable frame that protects the enamel fill. The neodymium magnet is fully encased in the brushed alloy backplate, preventing demagnetization or detachment under normal use.

Durability Highlights
· Hard enamel is baked, not painted — Each color cell is filled with molten glass enamel and kiln-fired at 800°C+, creating a glass-hard permanent finish that cannot peel, scratch off, or dissolve
· Gold borders are electroplated, not painted — The raised metal dividers are electroplated with real gold-toned finish and sealed with clear lacquer, ensuring the shine lasts for years
· Magnet is embedded, not glued on — The neodymium magnet is press-fit into a precision-machined cavity in the alloy backplate and secured with epoxy, preventing the magnet from falling out over time
· Backplate is shape-matched brushed alloy — The backplate is cut to the exact outline of the enamel shape (not a generic disc), giving a seamless look when displayed as a magnet
· No through-hole means cleaner design — Unlike traditional pins, the magnet attachment requires no hole through the enamel face, preserving the artwork integrity
· Colorfast pigments are UV-stabilized — All enamel colors and the red star detail are formulated with light-fast pigments that resist fading even in sunlit kitchens

Q: What is the minimum order quantity for a custom design like this?
A: For a brand-new design requiring a custom mold (your own bicycle shape, clock base, or layout), the MOQ is 100 – 300 pieces per design. If you choose from our existing bicycle pin molds and only change the enamel colors or clock numbers, the MOQ drops to 200 – 500 pieces. For a stock design with no customization, we accept as few as 50 pieces.
Q: Can this pin also be used as a fridge magnet?
A: Yes — that is the primary intended use. Each pin comes with a brushed alloy backplate that has a strong circular neodymium magnet embedded in the center. The backplate matches the exact outline of the enamel pin, so it sits flush against any steel surface. If you prefer a pin-only version without the magnet backplate, we can provide that with a standard butterfly clutch pin post instead.
Q: Can the clock dial numbers be changed to something else?
A: Absolutely. The clock dial currently displays the numbers "21" and "5" with Roman tick marks, but we can customize this to any numbers, letters, or dates you need — for example, an anniversary year, an event date, a brand founding year, or a product code. The dial color can also be adjusted to match your brand palette.
Q: What file format do you need for my custom artwork?
A: We accept AI, EPS, CDR, PDF, PSD, and high-resolution PNG (300 DPI minimum). Vector formats (AI, EPS, PDF) are strongly preferred because they allow us to create precision molds. Each color in your design must be on a separate layer so we can map it to the correct enamel fill.
Q: How long does a sample take to arrive?
A: Once the artwork is approved, we create the sample mold in 5 – 7 working days, produce the sample pin, then ship via DHL/FedEx. Total sample delivery time is typically 7 – 10 working days from artwork approval to your doorstep, depending on your shipping address.
Q: Can I get this pin in different sizes?
A: Yes. The product image shows three sizes: Mini (~28 × 32 mm), Regular (~40 × 45 mm), and Large (~55 × 60 mm). You can order any combination of sizes in a single run. We can also produce custom sizes between 20 mm and 80 mm by scaling the design proportionally — though sizes outside the standard three may incur a separate mold fee.
Q: Is the red star on the mail satchel removable?
A: Yes. The red five-pointed star is a separate enamel cell that can be changed to any color, replaced with a custom logo or icon, or removed entirely for a blank satchel. If you want to add a small brand emblem or text inside the satchel area, that is also possible as long as the detail meets our minimum line thickness requirement (0.3 mm).
Q: What quality inspection do you perform on each batch?
A: Every production batch goes through a 3-step quality control process: (1) In-process inspection during mold creation and enamel filling — checking for air bubbles, color accuracy, and metal border integrity. (2) Post-polishing inspection — each pin is examined under magnification for surface smoothness, color clarity, and edge finish. (3) Final functional check — magnet strength is tested and each pin is hand-checked for secure backplate attachment before packaging.
Q: What payment methods do you accept?
A: We accept T/T bank transfer (30% deposit to start production + 70% balance before shipment), L/C at sight for orders above $3,000 USD, Western Union for sample orders, and PayPal for small orders under $500 USD. All prices are FOB Shenzhen / Shanghai unless otherwise agreed.
Q: Do you offer custom packaging for retail display?
A: Yes. We provide several packaging options from standard polybags to premium gift boxes with window lids and foam inserts. For boutique retail, we recommend the printed backing card with PVC blister or the windowed gift box — both look excellent on shelf displays and enhance the perceived value of the product. We can also print your brand logo and product information on any packaging option.
