The Eva Solo drinking bottle can be used like a handy water bottle. In your bag, at the office and in your leisure time. It is completely watertight, can be refilled time and again, and therefore does not impact the environment. The drinking bottle is made of BPA-free plastic, which means that it contains no bisphenol, phthalates or heavy metals. The plastic bottle itself is dishwasher-safe. The screw-top lid must be washed by hand.
