Hearts and more hearts. The high-quality, recyclable VIVA drinking bottle is made of transparent polypropylene, making it easy to always see how much (or little) has already been drunk. All materials are recyclable and free of harmful chemicals, such as BPA, estrogen-mimicking substances and phthalates – for a safer drinking experience. The innovative ONE top makes the bottle especially convenient: carry, open, drink, close and seal easily with one hand only!
