30X30X60Mm Triangular Prism Bk7 Optical Prisms Glass Physics Teaching Refracted Light Spectrum Rainbow Children Students Present

The prism was sent the day after the order, received in 24 days. Adafar Saver Shipping in consolidated parcel with tracking to issue point. Packed in foam, Scotch and postal bag with air bubbles. Size: 30*30*30*59mm. The material is like glass, but the rainbow is not as easy to get as it seemed. Although I tried only from home bulbs and flashlight, as the weather will allow-I will definitely test the Sun) I can answer other questions about the product later, and if you need such a prism in St. Petersburg, please contact social networks: sfs_led
