5 star rating  Amazing Rainbows!
So many beautiful rainbows

5 star rating  best
Paulo Moreira Gomes from Cuiaba, MT - Brazil
excellent quality material. Up to my expectations.

4 star rating  Nice ROYGBI Spectrum for a Small Prism
Mike from Arlington, VA
The larger the prism, the larger and more discernible the light colors spectrum will appear. This is a small pocket prism, but the definition of the ROYGBI separation is surprisingly good.

5 star rating  awesome
Bookseller Guy from St. Paul, MN
Great simple small prism. Does exactly what it's suppose to do. Brilliant light refraction. Sits on my desk and looks cool.

5 star rating  Quick service, product as described
Greg Whelan from USA, Mi, Shaftsburg
It was exactly what we ordered. No issues with that. I functions as described as well, just be aware that a few feet between the prism and surface needs to be present to see the clear fraction of light

5 star rating  Glass Prism
Peter from East Brunswick, NJ
