You are looking at a set of Sesame Street themed training wheels featuring Cookie Monster and Elmo.  The package is sealed and was created in 1998, so there seems to be some slight yellowing on the vinyl bag.  The packaging says the size is universal.  A wonder addition to any little one's bike to get them riding for the first time.  Please view photo and ask any questions about condition before bidding.  Shipping is $12.00.  International bidders please use global shipping option.  Thanks for looking.
