To use this Crayola 3D Activity Set - Pets, start by coloring both the POPS art page and the background page with the 7 washable mini markers included. Once you're done coloring, carefully separate the art from the POPS art page. Then, take the tabs on the art and affix them into the slots on the background page. As you do this, you'll see the 3D artwork form right in front of your eyes. You can also use the stickers to add a personal touch to your creations. When it comes to storage, keep the set in a dry place to avoid the markers from drying out. If the markers start to run out of ink, you can gently press them on a piece of paper to see if the ink will flow again. This set is for kids aged 5 and up, so make sure younger kids are supervised while using it to prevent any small parts from being swallowed.
