The REMIX Shaker is a disposable, recyclable nutritional supplement shaker made in the USA that you never have to wash. REMIX Shaker consists of a patented custom designed plastic lid with integrated strainer that attaches to the included 20 ounce paper cup. The fixed strainer provides superior mixing and the wide spout is ideal for thicker protein shakes. The lids and cups stack allowing easy transport and easy storage. You can use REMIX anywhere and enjoy your own supplements while saving money. REMIX is cost effective because you dont have to pay ridiculous prices for ready to drink supplements. Better yet, you get to choose your ingredients. You dispose of or recycle the entire shaker when you are finished so no more washing or finding the hazmat suit to deal with a dirty shaker that you left uncleaned too long. Spend more time doing what you want to do and less time cleaning. Note: To use the REMIX Shaker, grip the cup closer to the bottom while shaking. This prevents the top part of the cup from collapsing which can compromise the seal. At the same time, lightly apply downward pressure to the cap and lid with your other hand. Also, do not use REMIX Shaker with carbonated supplements or supplements that "fizz."
