Grimm's Blue Wobbly Stacking Tower

Wonderful first stacker in cool blues and greens - hand dipped in water based, non toxic stains by Grimm's.  It's much more than just stacking, of course.  Lots of fun to discover that the rings can roll and be used as building blocks. Just the right size to take along on outings, too.  6 pieces.  Approx 5.25" tall. Ages 1+.  Linden.  Germany
