    Excellent quality. The glass is transparent, without any defects. A good red box for storage, it protects the product well.

    The prism comes in a typical Chinese box, which protects it from breaking. The prism allows the breakup of sunlight in the wide spectrum of colors. Tip: orientate the beam of light horizontal to one of the three sides. This will cast rainbow colors at the ceiling. A distance of several meters from the prism to the surface is required for the colors to be visible. Disadvantage: it could be a little cheaper. Quality is good.

    Very well packaged, and fast delivery. It should be noted that these are not a perfect equilateral triangle, and the length dose vary between the 3 I ordered. They do however break light into its component colours and show the rainbow effect. They come in a magnetically latched lined presentation box, a great gift for someone who likes experimenting with light and laser defraction.

    Prisma de cristal bien pulido y acabado. Es una excelente oportunidad para enseñar conceptos básicos de óptica o para experimentar con la luz. Muy bien protegido, en caja de cartón rígido y acolchado en su interior, y a un precio ridículo.

    Good price for a prism! Tested it, it works fine, I get a good light decomposition. It comes carefully wrapped in order to avoid breaking. I'm satisfied with this purchase! :)
