I'm so excited about these super cute sports bottles! They are 15 oz. bottles made of virtually unbreakable material. They have an everlasting pop up straw and a storage compartment that unscrews on the bottom - perfect for keys, money or a snack! Mommies on the go need them and so do all the kids!!! They make a great gift for anyone that plays tennis or sports. I love mine because it's cute and it will hold one full can of Diet Dr. Pepper! Choose any design from the website and I can make a super cute sports bottle for you!
