Reebok Crossfit Games 2015 Blender bottles brand new with tags. Comes with two screw on attachment containers for protein powder and/or supplements. Just fill with water and use the shaker inside for your post workout protein. Works great and so convenient. Additional screw on attachment can be used for supplements or leave it off if you don’t need it. I can’t live without mine and it helps me remember to take my vitamins. Usually sell for minimum $10 when on sale on their website but go up to $18. Selling in sets of 5!!! Will negotiate discount for more than 5 at a time.
