This device integrates a pencil sharpener and a mini desktop vacuum cleaner in a compact body. The two functions share the same motor and the same dust box so it is very practical and cost effective. It is mainly intended for students, designers and artists. The whole design is simple and approachable. The semi-translucent matte material let you observe the internal space while not cause visual clutter. The concave cover is magnetized so it is easy to open and close.
