This cool radioactive spinner has got the radioactive sign cut-out in the middle, with cut-out hexagons surounding it. Due to the double ring of hexagons, this spinner creates a really cool 'triple ring effect' where basically it looks as if there are three loops orbiting the bearing. It uses 22mm diameter bearings.
