Very special little box All aluminum alloy material This lock is not a decoration, it is usable. You can hear the locking sound when you pull it to both sides. You can put about 30 business cards inside. You can also put the most commonly used business card on it. The transparent piece can be seen clearly at a glance, and it looks like a mini password box. The workmanship is quite exquisite, and you can earn enough face by taking it out and handing out business cards. Size 100*65*16mm Please note: our store is a private customization store.
