此箱尺寸小巧，便於外出攜帶，亦可系繩背挎。此種形制早於拍子式，明代以前已流行。通體光素，立墻以銅條包鑲，起到加固耐磨的作用。兩側安方形提環，正面鑲長方形面頁，安鎖鼻，箱蓋關好後管狀銅飾件與兩旁的鎖鼻同高，可加鎖。

        The box is small in size, easy to carry around, and can be tethered back. This type of shape was earlier than the beat style and was popular before the Ming Dynasty. Through the body light, the vertical wall is wrapped with copper strips to enhance the wear resistance. The square ring on both sides is provided with a rectangular surface on the front side, and the nose is locked. After the cover is closed, the tubular copper fittings are at the same height as the lock noses on both sides, and can be locked.
