Chief Engineer's Note

20 Years of Structural Design Experience

This custom magnetic folding box is designed for small and light products such as car chargers and digital accessories. Made of 250-350g white cardboard, it features a smooth surface with true color reproduction and optimal stiffness to ensure the box remains sturdy and deformation-resistant. Dimensions: 180mm (L) × 70mm (W) × 35mm (H), perfectly suited for daily shipping and stacking needs. The printing process uses offset multi-color overprinting, clearly displaying product images, brand logos, and parameters (18W, Bluetooth FM transmitter) on the front and sides, with fine and exquisite text and patterns. Surface finishing options include matte lamination (premium texture, scratch-resistant and wear-resistant) or glossy lamination (vibrant colors, fingerprint-resistant), allowing your packaging to balance display and protection. As a custom product, you can adjust details according to brand needs to create a dedicated packaging solution.
