I debated about whether to buy this kit when my kids and I were doing a homeschooling unit on Ancient Egypt. I think I still would have bought it, if I had to do it over again. It wasn't really necessary, but I think the price made it worth it.
The kit includes four small Dover books (Egyptian stencils, Egyptian tatoos, two books of Egyptian stickers). My littlest kids enjoyed these the most. The stencils are not very sturdy, but the kids liked being able to make real Egyptian designs. The stickers are also not very sticky, but I think this is so you can use them over again.
The kit also has three masks, one of Pharaoh, one of Nefertiti, and one of a cat. I thought they were kind of creepy and small, but whatever. Also included was a small poster of King Tut's face mask, which is iconic of the whole subject.
The part I am not so sure about is the two larger Dover coloring books. There is one on Daily Egyptian Life and one on King Tut. Both are much harder than typical coloring book age kids... these are for upper elementary kids, ideally, with tiny spaces to design and color. The Tut one is more image friendly, but I found the Daily Life one to be slightly dark in tone... the Egyptian faces are kind of ugly, there is a two page spread with topless dancers, etc. But I'm kind of picky. If you have older kids who love to color, they are worth it. My kids couldn't really appreciate them. Plus, who really needs 48 pictures on just Ancient Egypt to color? They get the point after just a couple.
