So here's how I've been keeping my PES supps organized for my backpack. I stack them in this little spring-loaded sleeve, which I then decorated with a cartoon version of Nattydisaster's head on the actuator . All I have to do to get a serving of Shift, AT2, or Erase is tilt the cartoon head back, and one is pushed forward for me to take.
I call it a "PES dispenser!"
