Book of Questionable Knowledge Journal | Vintage Apothecary Cover

Own the official Book of Questionable Knowledge from Artificial Ingredients Laboratories. Whether you're documenting profound discoveries, terrible ideas, or evidence that seemed convincing at the time, this journal is ready for all of it. Wrapped in the official vintage cover from Mister E. Juice's collection, it looks like something recovered from the back shelf of a traveling medicine show—probably because it was.

Inside you'll find 128 blank pages waiting for observations, theories, recipes, inventions, sketches, and conclusions that may or may not survive public scrutiny. The flexible casewrap binding opens comfortably for long writing sessions, while the smooth 90 gsm pages welcome ink, pencil, or marker with ease. At a handy 5" × 7" size, it slips into a backpack, satchel, desk drawer, or the nearest suspicious-looking tent.

Because around here, every great discovery starts with someone writing down an idea that everyone else called ridiculous.
