Good glass, bends light strongly, have to learn to use it properly. They came intact.

I bought these as a gift for Our Grandchildren. Then really like to play with them and explain to their friends how these break down white light into different colors. A good science project to explain this and how the sun shines on a rain shower to make a rainbow.

These are nice, they come in a nice little box with a little cloth and have the nice factor. They are readily broken though and they don't put off much more of a rainbow in comparison to the class sets. Class sets are much more durable and a lot cheaper.

They will refract light if you get the angle right, but they should have used a more refractive material.
