Jelly Comb Foldable Keyboard

This portable Bluetooth gadget folds down small enough to toss in your backpack or other small bag, yet offers a full-function QWERTY keyboard when opened up. It also works in USB mode, and has a built-in touchpad, though that’s only compatible with Windows and Android devices. Measures 5.98″w x 3.82″d x 0.71″h folded.
