Nobody said that creating an all natural sports drink would be easy. It wasn't. As many of you have learned, protecting it from the environment isn't easy either. These are the challenges of using a real food product instead of one full of artificial colours, flavours and preservatives. Secure clasp closure protects your SDM from moisture/spillage. No more ugly plastic containers on your kitchen counter. Less waste - Reusable. Will hold about 1.5lbs or 28 x 500ml servings of any Skratch Labs drink mix. If you live in an area with high humidity we strongly suggest our Italian Mason Jars. Giving the container a good shake or stir everyday will also help to keep the mix from clumping. It's not always easy to avoid preservatives and anti-caking agents, but we think it's worth it.
