Ya know, I’m not necessarily being untruthful when I say it has infinite uses. Technically speaking, EVERYTHING has infinite uses. Think about it.
The Barely There Brush Mouse by Jang Woo-seok is an interesting take on your average computer mouse. It’s non-slip, super flexible, prevents hand fatigue, and has amazing airflow to keep your hands from getting all gross and clammy. It also gives you mini-hand massages when you move your palm.
I imagine you can brush your beard with it too.
