Using this mosaic kit is super easy. First, open the box and take out the 4 illustrated cards, 12 sheets of self - adhesive metallic foam squares, and the color step - by - step explanatory booklet. Look at the numbers on the cards and match them with the same numbers on the foam squares. Then, peel off the backing of the foam square and stick it on the corresponding spot on the card. As you go, you'll see the picture gradually take shape. When you're done, you can display your amazing creation. Here are some tips. Make sure your hands are clean before handling the foam squares so they stick well. Keep the booklet handy in case you forget a step. When not in use, store the kit in a cool, dry place to prevent the foam squares from losing their stickiness. And have fun creating your space battle masterpieces!
