Then, use the included 650 micro pegs to fill in the design on the high - definition grid. You can choose from 4 different light modes to add some extra detail to your art. When you're done creating, you can display your masterpiece in its retro packaging. As for maintenance, keep the set in a dry place and avoid getting the micro pegs wet.
