1 Box of 12 Coconut Puffs Built Puffs are here! What are Built Puffs, you ask?  Well, they are a bit of heaven on earth. Marshmallow heaven, that is.  The first and only collagen protein bar with amazing marshmallow texture, Built does it again.  It has a delicious texture, flavor, and, of course, it is covered in Built’s signature 100% chocolate. You will quickly forget this is a protein bar, thinking of it more as a tasty treat.  Feel good about that.
