Keeping a backup fully-charged battery on hand is always a smart idea! It’s even smarter when those batteries are Smart Batteries, like this Gold & Rainbow Smart Battery Duo.

The Ooze Smart battery is a simple, no-frills device that really does its job. It’s thicker than the usual Ooze pen and has a small screen on the bottom to check voltage and battery power. There’s nothing fancy about it, and that’s exactly why it’s such a staple. 

We noticed that our customers buy these two colors of the Smart Battery together most often, so we decided to turn it into a duo bundle! This way, you’ll save few bucks on the pens you were already going to add to your cart.
