Review on Essential Cosmetic Container: Organize Your Homemade Products with Style by Rob Overturf

Perfect size bottles, fairly strong, easy to assemble, no missing parts etc. However I only give the product 2 stars for functionality. Rollerballs don't roll easily. Even after repeated [trying] use, the rolling ball on many bottles will not roll without thumb effort (which is useless since most people want to apply oil from a bottle to parts of the body other than their body). Thumb.). A few rollerballs seem to work fine, but I would say at least 20 of the 24 included rollerballs were non-functional. Damn.
