Oh, we are all fond of the Teenage Mutant Ninja Turtles and the brains of operation, Donatello! Donatello is known for his purple color scheme and his skill in the bo-staff...he was also the team's mechanic! Somebody has to maintain the 'CheapSkates'! Those things are pretty awesome...say, where do you put your keys for your sewer-based craft? Might we suggest the 1.25 inch high TMNT Donatello Metal Keychain? Showing off Donny's immediately recognizable headshot, the TMNT Donatello Metal Keychain is one fantastic item!
