Check the listing for details. Educational Innovations Write & See Squares #SS-910 Fun Drawing Light Board •VG‼. Condition: Used. Listed at 9.95 USD. Educational Innovations Write & See Squares #SS-910 Fun Drawing Light Board •VG‼ Very Good Pre-Owned Condition! Little to no wear. Board measures approx. 5-5/8" x 5-7/8". Battery is working on the light, but I'm not sure how much juice is left. Move the blue light across the Write and See Square and observe the brightly glowing trail. Violet light has enough energy to excite the phosphorescent pigment in the vinyl. The excited pigment then slowly releases energy as green light (the "glow" look). Red Light does not have enough energy to affect the pigment. Contains a mounted sheet of phosphorescent vinyl ~15 x 15 cm (6" x 6") and an incredible Blue Photon Light LED flashlight on a key-chain ring.
