The width of the paper shredder inlet is 4.92"/12.5cm and the width of a torn paper is 0.12"/3mm. The hand paper shredder is only 6.69" x 3.74" x 5.91" (L*W*H), so it doesn’t need much space and fits easily on a shelf, desk, or in a small spot. It is suitable for office, school, or home use. Note: It cannot shred plastic, cards, or thick or soft paper (such as toilet paper, napkins, kitchen paper). The portable handle with a 1L transparent plastic window bin makes it easy to see when it is full; you just need to gently remove the lid to empty it. The bottom is equipped with 4 non-slip foam pads to prevent sliding. Because of its mini size, you may need to fold paper in half to fit into the opening, but it will still shred it in no time. Its limit is 2 sheets of A4 paper folded in half.
