Set of SmoothMove Classic Moving Boxes includes eight small boxes and four medium-size boxes. The assortment is perfect for packing a small office or dorm room. Boxes are made with a durable, double-bottom, double-end construction. Lids ship attached to prevent lid loss and then tear off for use. Built-in handles on the sides make them easy to carry. Pre-printed charting on the exterior offers a place to itemize the contents. No tape is required for assembly. Recyclable boxes are reusable for the next move. Boxes are made of strong, 32 ECT C-Flute, corrugated material.
