This is the third set of these little 5D diamond sticker kits that I have purchased. I purchased this kit so that I had a few fun crafts for my 5yo and 9yo daughters to do during the summer. We decided that we HAD to try them out today. It was a blast! I love that the kit comes with everything you need. Having individual stickers to do makes this purchase absolutely worth it! We each picked a sticker, started with one color and took turns using the tool. We used a post-it note pad and wrote the number/color of the color we were using for my 5yo (who just finished pre-school) so that she could utilize number/letter recognition while we were working on this project and she had NO problem completing her sticker by herself! With so many stickers in the pack, they will get good use out of it over the summer. Will DEFINITELY purchase more for home use and as gifts!
