An apple box is one of the most useful pieces of equipment on a set! They are the ultimate multi-taskers and are used for propping up furniture and light stands, leveling camera dolly tracks, or providing temporary seats, workbenches, or stepladders. Kupo apple boxes are made of high-quality birch plywood, built for long-lasting use. This set includes one of each size: pancake (20in x 12in x 1in), quarter (20in x 12in x 2in), half (20in x 12in x 4in), and full (20in x 12in x 8in), all featuring a neutral wood color smooth finish. Each box has rounded-edge ergonomic hand and finger grips for easy handling. Internal supports are equipped in the three larger size boxes, ensuring extra strength and dimensional stability. The brace of both side panels is for thread wires, poles or others gears through box if needed.
