Easily keep track of (benched) moves, health/life points, buff/debuff turns, card in deck (draw) %, so many things you can quickly keep track of in a duel/battle/caster throwdown! You can use it as a notepad as you're solving in-game puzzles, brainstorming, etc...The battery is replaceable, and the manufacturer boasts appx. 200,000 uses/"erases" per battery, VERY cost effective and waste reducing!

Another great, cost effective, way to entertain
children or individuals fond of drawing!
