Hold these life-size human x-rays up to the light or use them on a light table (sold separately) and see details of a real skeleton. Arrange them together to reproduce the entire body of a 5' adult. 18 pc. Set. Ages 5 yrs. +.
My kids and I spent a whole afternoon holding these up to the living room window and piecing together the full skeleton - fitting the arms and legs together to form the complete 5' body was way more fun than I expected. The details on the ribs and spine are sharp enough to actually count the bones,
Honestly, I was a little skeptical about how cool these would be, but piecing them together to form the full 5' skeleton is genuinely impressive. The detail on the ribcage is crystal clear when you put them against a bright window, and they're big enough to feel like a real anatomy lesson.
Held the skull sheet up to my window and the suture lines are surprisingly crisp for the price. Took a star off because the sheets curl a bit if you leave them rolled too long, but a night under a heavy book flattened them out fine.
