Size: (Outer dimensions) 31cm (height) x 24.5cm (width) x 1.5cm (thickness) - Color: Yellow - Color: Orange - Color: Blue (not shown in the photo) - Color: Clear (the clasp is weak, so consider it a bonus. This one is 1cm thick only) Specifications: One side has a clasp like a clasp purse, which can be opened with a snap using your thumb and index finger. When the clasp is opened, it opens wide, and you can carelessly throw in A4 documents until it's full. When closed, the corners of the A4 documents will naturally align by shaking the box. The back side (opposite the opening side) does not open about 2.5cm, which holds the documents in place. If you press the middle slit with your thumb, you can manually secure the back side of the documents inside, which is convenient for opening the clasp and flipping through the documents. It's convenient as a temporary storage place for documents that are frequently taken in and out, before you punch holes in them or temporarily clip them together. Although you need to use both hands, it's easier to take documents in and out than with a clear file, and you don't have to worry about the corners getting bent. It's made to A4 size, excluding the clasp and the 2.5cm back, so clear files will not fit. I'm selling these to reduce plastic use. I can't offer a discount because the shipping cost is already at the limit. Thank you for looking.
