Other than the product literature, the only “stuff” seems to be the shaker, which is just a wire ball designed to break up your pretentious protein powder add-in. Unless you’re counting hte lid as extraneous “stuff”, of course.
ETA: I should read all the pick-shoors before I make comments. Shaker looks like a cocktail model, not a no-handle wire whisk. Still…not much extraneous stuff.
Mea culpa. Or something.
