Product Overview
Bincai’s magnetic rigid gift box for premium electronics is engineered for brands that demand unboxing excellence. The precision-cut EVA foam insert cradles headphones, smartwatches, earbuds, or accessories with zero movement during transit — every cavity is CNC-machined to ±0.5mm tolerance. A soft-touch matte finish and dual N35 neodymium magnets deliver the tactile premium experience consumers expect from brands like Apple, Bose, and Sony. Manufactured in our Foshan smart factory (18,000 sqm total across two facilities) with Heidelberg 7+1 UV offset and KBA 1050 4-color presses. 80+ skilled workers, 23 years of packaging expertise since 2003.

Frequently Asked Questions
Q: Can the foam insert be designed for multiple device models in one box? A: Yes. Our CNC routers can profile multi-cavity inserts that accommodate different device generations or a device + accessories (charger, cable, manual) in a single tray. We provide 3D renderings for your approval before tooling.
Q: What is the lead time for a custom foam mold? A: Foam tooling takes 5–7 working days. We include digital 3D mockups within 48 hours of receiving your device dimensions or CAD file.
Q: Can the box exterior be branded with my company’s PMS colors? A: Absolutely. Our Heidelberg 7+1 UV press handles up to 7 Pantone spot colors plus UV coating in a single pass. We match any PMS color with spectrophotometer verification and provide color drawdowns for approval before production.
Q: Is the magnetic closure strong enough for heavy electronics like over-ear headphones? A: Yes. We use dual N35 neodymium magnets rated at ≥4.5N pull force per pair. For heavier products (300g+), we upgrade to N42 magnets (≥6.0N) or triple-magnet configurations. We test every unit on the magnet pull-force gauge at Gate 5.
Q: What is your sample policy? A: We offer free digital 3D renderings (48 hours) and physical hard-proof samples via DHL/FedEx (7–10 days). Sample cost is credited against your first production order. Rush 5-day samples are available with a $150 surcharge.
Q: Can you do full-color CMYK printing on the box interior? A: Yes. Both exterior and interior can be fully printed on our Heidelberg press. For maximum luxury impact, we recommend a black or charcoal interior wrap with gold foil brand logo — massively elevates the unboxing experience.
Q: Do you offer fulfillment and kitting services? A: Yes. Bincai provides value-added services including product insertion, accessory kitting, barcode labeling, and drop-ship directly to Amazon FBA, your 3PL, or end customers. Our 18,000 sqm facility has dedicated kitting zones with QC oversight.
