Prism Six-Sided Bright Light Combine Cube

Watch out! Prism very small.

Small reflective cubes, the shipment was fast, but one arrived broken, anyway it is highly recommended and meets its function despite its small size

The item does not match the picture at all. This "cube" has a size of 1x1x1 cm. While in the picture it is much larger. The product itself took 3 months to Moscow, which is well for a very long time. Opened a dispute, the seller does not answer at all. In the end it came, but it did not cost 3 months of waiting, as well as its money (203r).

16 days to Moscow. A good device to show children what refraction is and what light consists of.

Dimensions would immediately be prescribed was not bad... I thought he was a little more, but promised does :)
