Soda can? Wrongzo. The My ECO can is a reusable, refillable, resealable container. Only instead of aluminum they’re crafted of a biodegradable material called PLA (PolyLactic Acid/Corn Starch). The lids can snap open and closed, and because of their size, 9.5oz, they’re a perfect fit for any car cup holder. The thermal double wall design keeps beverages hot or cold, and it’s completely microwave friendly. The only downside is that each one appears to cost $14.
