Sold By Hamleys. With Window Art Princess, your child can now create and enjoying the craft activity. Children love to play with colours and clay. And being able to create their own little awesome Unicorn using fabulous colours of the easy to use Dotz clay is just so exciting. This Pack comes with 1 Sticker and 4 vibrant colours. The selection of 4 colours are perfect for the theme. The whole activity is so easy that even 3 year olds love it just fill, peel and stick. Once the stickers are made, just turn them upside down and gently peel off the silicon paper. Place the stickers on to any smooth surface like, glass, mirror or tile. Once you re ready to change the look of your room, you can simply peel off the sticker and place a new one. Dotz is an AIR DRY material. We have packed it in small pouches to help you consume a whole pouch once you open it . In case you wish to save an opened pouch, be sure to pack it in an air tight container (it can last for 48 hours). Butterfly Window Art is a great indoor activity for the kids. It is a great option for party gifts or return gifts as well.
