The bottle consist of a glass insert and a see-through BPA and Phthalate-free plastic sleeve that allows you to view the contents.
I've been reading some customer reviews about this product, and I found out that there are 2 primary areas where the design could be improve. First, there are not many threads on the base, so that you only have just over one turn to secure it in place. Second, the volume markings are somewhat variable between bottles and not super accurate.
