Using this Lite Brite is easy. First, place the design template you want on the grid. Then, start inserting the colorful mini - sized pegs into the holes to create your art. You can choose to use one of the 8 HD design templates or let your imagination run wild. After you've finished creating, turn on the light. You can switch between 5 different HD light modes to see your art light up in different ways. Remember, this product requires 3 AA batteries, which are not included, so make sure to get some before using. When it comes to maintenance, keep it in a dry place and avoid dropping it. If the pegs get dirty, you can wash them with mild soap and water. To display your art, you can use the stand on the back of the unit or hang it on the wall using the keyhole.
