Yes they are! The quality of your custom water bottles and the health of your recipients is of great importance to us, so we make sure that all of our personalized plastic water bottles are BPA free and FDA compliant. We use a variety of different plastics for different bottles. Some are flexible so you can squeeze your water into your mouth waterfall style, while others are transparent and made to keep their shape under pressure. No matter what plastic we use, however, you can be sure we always use plastics that are BPA free and safe to use.
