I received this as a prize, but I'm selling it because I don't have an opportunity to use it. The outer box and instruction manual are not included. I tested it to see if it lit up, and then kept it at home. ●Size: Approx. 40 x 20 cm ●USB powered, with an ON/OFF switch ●Confirmed to light up (see image 1) Although it has been barely used, there are some areas where dirt has gotten into crevices and cannot be removed. (It's like the examples in images 18 and 19.) Also, there are some areas where the packaging plastic has gotten caught and cannot be removed. (See image 15.) Additionally, there may be minor scratches and scuffs from storage. For the reasons above, please only consider this if you understand that it is a used item.
