These are the first rockets that Meesha and Devin actually built. They are kind of unique in that they come with multiple fins, you can unscrew the bottom and remove the fins and replace them with different types.
I've not seen anything like that with any other rocket so it's pretty cool. If you look closely you can see each rocket has a different fin set in it in the picture.
