One-off parts for specialised K'NEX sets
Our definition of a "one-off" part is a K'NEX part that has been designed for use with a specific K'NEX set, and which cannot therefore easily be used with other K'NEX sets.
One-off parts for recent K'NEX sets may be found in the K'NEX Spare Parts Service section.

Note that these are all new parts - we do not sell used KNEX.
