4 Corner Box

1. A Factory Built on Years of Hard Work

We began in the printing and packaging industry in 2000 and officially established Wenzhou Zhenfa Packaging Co., Ltd. in 2019. Our factory is located in Longgang, Wenzhou, China's Printing City, covering 5,000 square meters with 60 skilled employees and 6 Heidelberg printing presses. We support both OEM and ODM services. Every 4 Corner Box undergoes strict quality inspection, including print color checks and verification of the pre-glued corners, ensuring each box meets your standards.

2. A Strong Box That Keeps Its Shape

Made from single-layer cardboard, the four pre-glued corners make this box stronger and more durable than standard boxes. It features a hinged lid that stays attached to the box body, so you never need to worry about loose or lost lids. The box ships flat for easy storage and pops open instantly when needed. It is ideal for electronics such as phone cases, power banks, and small speakers, as well as cosmetic gift sets.

3. Quality Checks and Reliable After-Sales Support

We offer free samples of existing boxes, and custom samples can be produced within about one week. The sample fee is refunded once you place a bulk order. Our quality control is rigorous: every box is checked for print accuracy and structural integrity. Boxes are flattened and packed into sturdy cartons for safe shipping. During production, we provide regular photo updates, and our team is available for both pre-sale guidance and after-sale support, ensuring any issues are quickly resolved.
