Why Bincai?
Bincai’s magnetic closure expertise comes from 22 years of producing premium rigid boxes for global eyewear brands. Our integrated in-house magnet installation line ensures consistent closure force and hidden-magnet aesthetics — no visible magnet pockets on the exterior. The flocked insert tray is cut and flocked in-house, eliminating the 3-5 day outsourced lead time that delays competitors. For eyewear brands, this means one supplier for the complete box, insert, and packaging system — reducing per-unit cost by 15-20% versus multi-vendor sourcing.
