Love 'em or not, the mason jar is having its moment — and has been for some time. If you have a cabinet full of these versatile containers (we do!), here's a new suggestion for making them useful: the Cuppow. It's an inexpensive add-on accessory that makes your jars mobile — drink from them on the go without fear of spilling. The Cuppow is an eco-friendly, recyclable lid that sits on top of a standard jar; simply twist the ring cap tight to secure the lid.

You can get your hands own your own for just $8. A simple, practical, and creative solution: we love it!
