I bought the three pack to use for shampoo, conditioner, and facial cleanser. Turns out you can't store certain products in silicone. Still using for cleanser. Might use the other two for catsup and mustard later!
Other than the unpleasant surprise that I can't use them as I had hoped, the containers are great! The extra safety feature that allows you to secure the lid with the loop from the neck helps keep it from opening up during transport.
