This charming little hedgehog design from Grimm's Spiel & Holz Design is easy for babies to grab a hold of and safe for teething.  Wood feels good with its warmth and distinct surface.  No additives are needed to make it safe because its surface binds humidity - it is open and rough.  And on this dry surface bacteria cannot grow, so wood is ideal for making teether and grasping toys for little ones.  Attaches easily to the baby clip, sold separately.  2 3/4" x 4 1/4".  FSC Certified Alder.  Bosnia
