The Leofoto Folding Portable Mini Tray is a slim platform that can be attached to various stands, tripods, ball heads, and other supports. It attaches to these via a 1/4″-20 threaded hole on the bottom and allows you to place a phone, tablet, or other device or object on top. When you’re done, it folds in half and can be placed in a bag or even a large pocket. When opened, it measures 9.8 x 6.7″.
