How do you tell them apart small parts and bog ones

Many of the K’NEX kits include both small and bigger parts for certain projects.

Are these the big or small ones?

Hi there, these are the Classic sized Knex (larger). - Your Friends at Basic Fun

Does this work with legos?

I know some sets we have work with Legos but am not sure this one does. My grandchildren use both a lot to make their creations.

How do I go about getting missing pieces?

I would contact K'nex if you have missing pieces.
