it's a pillow with a see through window with beads in it. With in that it has little trinkets that are different from the beads (i.e. mine has a snowglobe eraser in it) with a list of what to find in the pillow. They are fun!!
I have saved 2 of Jeff's Gatorade bottles and washed them out real well. I am trying to find little stuff to put in and then going to use packing peanuts or something similar for the ones I am making the girls. I might have to look for cute small erasers. those would work. I have snaged a couple of the girls play rings to put in so far.
