BookArc by Twelve South
Compared to your MacBook lying flat on your desk, BookArc takes up a fraction of the space giving your workspace a clean, less cluttered look. Its soft silicone feet provide sturdy footing that won’t leave marks on your desk. Underneath BookArc are two hidden cable managers that prevent your monitor, USB, and power cables from slipping to the floor when you unplug your MacBook.
