## Description

Product description

Review: Good quality - Used for a reading lesson about light and the class loved using them. Good quality!
Review: Quality prisms in a nice package - These prisms are quality glass and work well for doing optical tricks and effects. The edges are chamfered a little so they aren't sharp. You can indeed get a rainbow but it just takes a while to get the right angles with sunlight, and you want to aim the rainbow in a dark area for contrast. Also, the prisms are packaged well and include a cleaning cloth. You'll need it for fingerprints.
