The prism is fine other then a small chip where the paper they wrapped it in caught a corner and ripped. It still works (kind of hard not to) but I wouldn't let small kids play with it since it could cut little fingers if your not careful...

I wanted an evenly shaped triangular glass prism to show the light spectrum as a physics demonstration. The prism I've got had several chipped pieces of glass near the edge of the prism. More upsettingly, the edges were uneven essentially, the prism was not really equilateral as specified.Per my request of a refund the seller replied:
"We are sorry that the item is not exactly what you expected. Per the description of this item we do state that it may contain small chips and/or defects. We have checked our current stock and most if not all of them have some sort of chip and/or defect in them which is why we list it as such."
So, I've spent another $3 to mail the thing back, and got $9.95 refunded. Seller retained their "shipping" charge of $6.95.
Bottom line: I would not recommend buying items from this seller, unless, of course, you are looking for items with "chips and/or defects."

Optical prisms are extremely expensive. I have never had a prism in my HS classroom supplies that was as nice as this one. ...a very nice weight. It's glass!!! Great for the scientific minded precocious child!!! The equilateral prism is the best for general light color spectrum demonstrations. Would not recommend for younger child. They might hurt themselves.
