MOXOM MX-VS61 360° Rotation Magnetic Phone Holder

A flat magnetic pad that folds out into a stand and folds back into something the size of a coaster. Closed it is a disc on a base; open it holds a phone at a reading angle, and the plate turns a full 360 degrees underneath so portrait and landscape are a twist apart.

MOXOM's two words for it on the box are steady and non-slip, which between them are the only things that matter on a desk stand: the base has to stay where it was put when you pull the phone off it one-handed.
