Since we have other K'nex Titanfall sets, this was compatible with those. It is one of the things that I really love about the K'nex Titanfall line. They are all interactive and completely interchangeable.
This K'nex IMC Atlas Titan Building Set would make an awesome holiday gift for any child! It is available on the K'nex site.
Go to the K'nex site and check out all of the great products they have to offer! Be sure to Follow them on Facebook and on twitter! They always have amazing offers and deals!
