I recently purchased a paperweight with various specimens for my desk at work.My analysis of this product showed that its a fantastic way to have a little bit of nature in my industrial and scientific environment. The specimens included in the paperweight are beautiful and educational. It's not too heavy to move around and I find myself lifting it up to examine the different pieces often. The only con is that the specimens may not be identifiable without additional research or knowledge. Overall A great addition to any desk!
