CMY Colorful Cube, 3.93 inch (100mm) Acrylic Mixing Color Cube Prism for Physics Education Learning and Office Desktop Decor, Scientific Toys and Gifts for Kids

These are very colorful and beautiful - the color mixing is really bright. This is a great desk accessory or fun fidget. They are acrylic cubes so kids can play with them, and it’s fun to explain the science behind them. I recommend getting more than one so you can make even more colors!

This elicited oohs & aahs when opened. A neat item for curious young minds & for adults young at heart. A great desk toy to give your eyes a break from screens. This is a slightly bigger size & I think my nephews liked having the larger cube to look through.

My Son loves this cube. So, this purchase made me happy. Good seller, too.Only drawback to the product is that the colors have started to peel off over time.No biggy, tho. It's value has been effective. Approved.

My wife is a graphic designer, she loves this cube, it's on her desk as part of all her designer toys.Solid one piece cube, size as specified in website, fun colors

a must have for anyone that enjoys light and color. I'd suggest getting a stand or holder for your cube as well.

Film started coming off after an evening of handling it. It's just a clear cube now with no colors.
