Purchased for my 5 y.o. great-niece for Christmas and it was a HIT. Her parents report that this has been her go-to project whenever she has a bit of down time (not sure if she's completed it yet). Have purchased many of the sticky mosaics and have never been disappointed. Sure, some of the stickers don't stay on forever but for the cost and the hours of fun kids get from the kits that's not an issue in my book. Great item.
