Review on Ajax Scientific Refraction Equilateral Length Science Education by Nathaniel Collins

glass quality is poor. The item was packaged and well sealed in a small box in a box, but one corner of the prism was broken off and there was a scratch on the side of the prism. It looks like the manufacturer mishandled it before sealing it in an Ajax Scientific Glass box. Revain packaged the product very well. The damage occurred before Revain packed this item. The Prism is still serviceable, but it's always disappointing when you pay for an item and it arrives scratched or slightly damaged when you expect it to be brand new.
