Great window rainbow maker

Heavy and good quality. Have these in my window to catch light and make rainbows. They just have to be angled right.

Great Quality, Great Presentation

I purchased this set of prisms to conduct experiments in optics for a physics class. The prisms had no chips or blemishes and were beautifully packaged. I wouldn't hesitate to gift this to a science teacher that's how attractive the packaging is. Great product.

Awesome!

The prisms themselves are great. They are well made and made of glass, which I think is a lot nicer than a lot of the others ones on here that aren't. Also, they come in a pretty nice box; however, they do put stickers on the box so don't expect that to be too nice.

Great value, refracts light and works well for prism photography

Excellent value for the price. While not exactly optical-quality as expected, the prisms work to refract light into component rainbow spectrum.

Science teacher's dream!

well packaged and the glass is much more effective than the acrylic options out there. Worth the money for any science teacher out there!

High-Quality Glass Prisms

I am very impressed with the quality of these glass prisms. The edges are very clean and straight, and the glass is very clear. They arrive in a well-padded case that opens as a “display”, which can serve as a storage container. They appears to be an expensive product.

Five Stars

Put them in the sun and view the beauty of a rainbow.

Great way for my grandson to learn about photons and light waves!

My grandson saw someone on TV using a prism and asked me if it was real of "fake news" (Ah the tragedy of where our "president" has taken our society's reality!) The prims arrived FAST! They are perfect made and do their job. He is so jazzed about it he nows goes around looking for sunbeams to work their magic. I highly recommend these prisms. The work better than the acrylic ones, they have no internal irregularities that will affect the light coming oout of them.
