Sand Art is a fun way to get your little ones (and even the big ones) to fine tune their skills while still having fun. There is no need for messy glue because the adhesive (sticker) is already on the pre-cut cards. You just start by peeling an area of the picture and then pour the extra fine colored sand, which will stick to the card Peel the next area and use another colored sand and repeat this until the card is completely colored. The end result is beautiful and will last forever! The gift pack comes with 4 postcards plus a laminating feature. With more than enough sand to color all the postcards and with step-by-step instructions, it's easy to create a Sand Art masterpiece!
