This personalized water tracker bottle is super easy to use. Just fill it up with water, and you're ready to go. The time markings on the bottle can help you keep track of your water intake throughout the day. It's great for everyday use, whether you're at home, work, or out for a walk with your pet. When it comes to maintenance, remember this bottle is not safe for the dishwasher. Instead, wash it by hand with warm water and a bit of soap. This will keep the bottle clean and make sure the 3D inflated effect print stays looking good. And don't forget, this bottle has copyrighted artwork, so it's a unique item. It's not a real 3D bottle but a flat - surface one with a 3D print, which gives it a really nice and premium look.
