This mobile is lovely -- beautiful design and quality craftsmanship. The storks are made of something like a thick cardstock. Other reviewers have complained that the construction of other mobiles by this maker are 'flimsy,' but I do not have a problem with the thickness of the paper. I do not think they are designed to be handled, so I would plan to hang out of kids' reach. The storks gently rotate all the time, and look especially cool from below (my son's point of view in his crib!) Also the black and white are great color choices for newborns (they see strong contrast best)--overall a great alternative to the typical musical mobiles that are expensive and not that attractive.
