Frequently Asked Questions
Q: What is the MOQ for custom portfolio presentation boxes? A: Standard MOQ is 500 units. For premium leather-wrapped configurations with multi-level embossing, MOQ is 1,000. Prototype orders of 100 units available with tooling surcharge.
Q: Can you incorporate our corporate brand guidelines into the design? A: Yes — we match Pantone brand colors, reproduce your logo in foil stamping or embossing with ±0.15mm registration, and follow your brand typography and layout specifications. Free brand compliance review included.
Q: What file formats do you need for the foam tray design? A: 3D CAD files (STEP, IGES, or SolidWorks) are ideal. If you don’t have CAD, we create the foam cavity design from your product dimensions and photos — free of charge.
Q: How durable is the magnetic closure over time? A: Every production batch undergoes 1,000-cycle open-close endurance testing. N52 neodymium magnets maintain >95% pull force after 1,000 cycles. For ultra-heavy-use corporate applications, we recommend the optional metal clasp reinforcement.
Q: Can the document sleeve hold multiple pages? A: Yes — the 0.3–0.5mm PET sleeve accommodates 5–15 sheets (80gsm) depending on thickness. For thicker brochures or booklets, we can upgrade to a 0.7mm PET sleeve or a die-cut cardboard pocket.
Q: What is the turnaround time for a corporate event order of 2,000+ units? A: Tooling 10–18 days + production 18–25 days = 28–43 days total. Expedited 15–20 days available for time-sensitive corporate events. We have fulfilled 5,000+ unit corporate event orders within 3 weeks.
Q: Can the box be branded on the inside as well as the outside? A: Yes — full-wrap interior printing on inner lid and base panels. Foil-stamped brand message inside the lid, embossed pattern on interior surfaces, and custom-printed foam tray lining are all available.
