Why has the paper cup hung on so long? Well for one it is convenient, but I think its more than that. My guess, we have grown accustom to the look and feel of the paper cup. The traditional cup fits in our hands easily, doesn’t readily spill and is evenly contoured. For all of you looking for a great, affordable, reusable, option, look no further than the brand new Eco Cup. They are out now and only $9!
