They are also known as "natasha" beads or an "inside out" bead. I call them guardians because sometimes I can see angels, animals or faces in them. They are like a Rorschach test and everyone sees something different in them.
They are scraps all mushed together, formed into a log and cut open to reveal the picture inside. When cut the right way and opened up the right way all of the sides and middles match up.
Kind of fun and addictive to make because you never know what you are going to get.
