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 ony collargen protein bar with amazing marshmallow texture. Built does it again. It has a delicious texture, flavor, and, of course, it is covered in Builts signature chocolatey shell. You will quickly forget this is a protien bar, thinking of it more as a tasty treat. Feel good about that.
