Review on Mziart Portable Silicone Bottles Containers: Travel-Friendly Must-Haves for Convenience and Hygiene by Sonja Garcia

I like these sizes. The roundness makes it easy to store and use. I would say that you need to wash them very well with soap and let them dry completely. They have a gummy odor that takes a bit of effort to get rid of the first time you use them. In addition, they are great for a diaper bag with creams, soaps and other necessary items. I haven't had any leakage issues. I traveled with coconut oil in it and not a single drop came out.
