Q: Can we do double-sided designs on the 3D metal charms or are they flat on the back?

A: Standard manufacturing utilizes single-sided 3D modeling where the front features raised metal and enamel infill, while the reverse side is flat with a recessed sandblasted texture suitable for laser-engraving a secondary website URL or social handle. Double-sided 3D designs require building a two-part mold and doubling the metal injection volume, which increases the tooling setup cost.

Q: How durable is the color plating if the keychain rubs against keys and zippers all day?

A: Items undergo an electro-deposition plating bath followed by a clear lacquer protective coat to prevent surface wear. While natural brass or steel will eventually show slight edge fading after months of heavy friction against metal keys, the nickel and antique finishes hold their color extremely well without flaking or exposing the raw zinc base.

Q: What is the exact process for matching our brand colors to the enamel paint?

A: You submit a vector file featuring standard Pantone Solid Coated references. The factory color-matching technician mixes liquid enamel pigments under a light box to hit the reference within a delta E variance of less than 2.0, sending a high-resolution photo of the wet enamel sample for your approval before filling the entire batch.

Q: Can we change the standard keyring attachment to a lobster clasp or ball chain later?

A: The attachment hardware is completely customizable during the assembly phase. You can swap the 30mm split ring for a rotating lobster clasp, a leather loop, or a silicone strap depending on how the charm needs to interface with the target bag or accessory line.

Q: How are the items protected inside the master carton so they do not get scratched up during the boat ride over?

A: Every charm is individually dropped into a clear polybag before being grouped into larger bundles. The master boxes are packed tight with dense styrofoam lining the interior walls and reinforced with heavy-duty polypropylene strapping bands to prevent crushing or box collapse during rough ocean transit handling.

Start with this — a 3D zinc alloy charm. It’s not flimsy plastic. You get to design any shape (your logo as a mini 3D figure, a cartoon mascot, whatever). Send them a sketch or reference, they’ll create a mold. At 50 pieces MOQ, you’re not risking thousands on an experiment.

Event / convention organizer

“I'm planning a gaming convention and need cool swag for VIP tickets. Any ideas?”

 Metal backpack charms. Seriously. Attendees will clip these to their lanyards, bags, or key rings — not toss them in a drawer. The 3D zinc alloy ones have weight, feel premium, and you can screen print your event logo on the back. Go with something cute or pixel‑art style for gaming events. MOQ is low enough to test.

Customization question

“Can I put my logo on both sides of the keychain?”

Yes — screen printing can go on one side or both. The 3D shape is the main feature, but you can add your logo or text on the back of the charm. Just specify when you send your artwork. Extra cost is minimal for bulk runs.

Quality / durability

“Are zinc alloy keychains durable? I’ve had cheap ones break.”

Zinc alloy is tough — it's die-cast, not hollow plastic. These can handle being clipped to a backpack that gets tossed around, or keys that jangle in a pocket all day. The screen printed artwork holds up too. No flaking after a few weeks.

MOQ / small order

“I only need 100 pieces for a launch event. Is that possible?”*

 Yes — MOQ starts at 50 pieces. At 100 pieces you unlock full logo printing. That’s perfect for a small brand launch, a wedding favor, or a club giveaway. Price per unit is a bit higher at small quantities, but way better than paying for 5,000 you don’t need.

Anime / character design

“I do fan art and want to turn my character into a real keychain. Possible?”*

Absolutely. That’s exactly what 3D die‑casting is for. You send a 2D drawing or a 3D model (or just describe it). They create a mold, cast it in zinc alloy, plate it, then add color with screen printing. Small MOQ for test runs. Many indie artists start exactly this way.

Teacher / classroom gift

“I want to give my students a little backpack charm at the end of the year. Cute, not expensive.”*

Great idea. Mini animals, stars, hearts — simple 3D shapes keep the mold cost low. Zinc alloy charms feel nicer than plastic, but at 100‑200 units, the price is still reasonable. Kids will actually put them on their backpacks for next year. Your class year or a small message can be printed on the back.

Price / bulk order

“What’s the price per unit if I order 5,000 of these?”*

At 5,000‑19,999 pieces, price drops to around HK1.59perunit( 1.59perunit( 0.20). At 20,000+, it goes down to HK1.03( 1.03( 0.13). That’s a steal for a solid metal charm with custom 3D shaping and full color printing. Great for large festivals, retail loyalty programs, or national brand campaigns.

First‑time buyer / nervous

“I’ve never ordered custom merch before. How do I avoid messing up?”*

Order a sample first. Always. Send your design, pay for a mold (usually one‑time cost), and get a few physical samples in hand. Check the weight, the print, the clip. If it looks good, then place the bulk order. This supplier does 3‑7 day samples — fast enough to keep your timeline moving.

“Do these come in nice packaging? I want to sell them in my shop.”*

 Standard is OPP bag (clear poly bag). But you can upgrade: custom printed boxes, velvet pouches, or backer cards with your branding. For retail, the box matters — people pay more for something that feels gift‑ready. Ask about custom packaging options when you request a quote.

Backpack vs key ring use

“Is this only for keys, or can it hang off a backpack too?”*

Both. Comes with a split key ring and a link chain. That means it's ready to clip onto a backpack zipper pull, a purse strap, a pencil case, or a keychain. The lobster clasp style makes it easy to move around. Most customers actually use them as bag charms — keys are the second use.
