How to make plain, reusable jars simply look awesome? With Cuppow ($8). This brilliant little tool acts like a coffee cup lid, working with most normal wide-mouth canning jars to turn them into efficient, eco-friendly, reusable and spill-free travel mugs.
Cuppow is made from BPA-free and phthalate-free food grade polypropylene, and comes in different sizes.
I've seen questionable drink paraphernalia before, but the Cuppow is definitely a practical accessory for the modern foodie. At worst, it's something like a grown-up sippy cup, which actually sounds like a pretty cool idea in itself...
