Bungie is selling engrams in its official store now. You can get a four-pack of engrams with one green, one blue, one purple, and one yellow, for $19.99. Actually, they’re stress balls–you know, those squeezable foam things. Each ball is about 3″ x 3″ and come in a clear plastic display box.
Evidently supplies are limited, Bungie warned us on Twitter, so don’t sit on your hands if you absolutely need to have an engram stress ball in your life.
(Update: Engrams have apparently sold out already. Maybe they’ll come back due to high demand.)
