I like to use this refillable/reusable container for my home made toothpaste. It makes it easier to than putting it into a little jar. The container is pretty easy to fill, the opening is nice and wide. I have only had a small problem with anything leaking out of the container, and that I think was due to me not putting the top on very well. For the most part, everything is nicely contained. I received this at a discount for review purposes.
