I have only used this light box once.  It is in Like New condition.  When held horizontally the box measures 11 3/4" from left to right, 8 5/8" from top to bottom and 2" deep.   Box comes with a cable that has a 5V plug that goes into the box and the other end has a USB plug in that can go in any USB plug.  Box comes with 200 letters, numbers, symbols, and emoji type pictures.  Letters, numbers and symbols come in black, pink, purple, green, blue and orange. (Not every letter in every color).  The pictures range from hearts, smiley faces, pizza slice, wine glass, rainbow, dog etc....
Instructions sheet included.  Batteries Not Included.  USB cable included but not the part the cable goes into that goes into the electrical outlet.
