I purchased this for my daughter, and we had a great time putting the stickers on.  She's four, and I think that was the perfect time for her to follow the number grid directions - a year ago, she wouldn't have cared and would have just stuck stickers wherever she wanted. That's fun too, I guess!  The only problem we had with the box is that the stickers came off relatively easily.  They seemed pretty rugged at first but we had a lot fall off.  I was very disappointed because it was such a fun project and my daughter was excited about putting her treasures in the jewelry box (the box is fairly rugged as well and would be perfect for little girls).  To be fair, my two year old son helped some of the stickers fall off, so if there are no terrible toddlers around, you may be ok.  I would buy it again and keep it away from my son!  When you put the stickers on, make sure to put them on very firmly.  This was hard for my daughter to do, so you may want to just go back and press on each one she puts on.  This may help a lot.
