So here's some pics of my potion Rod - it is 9" long, made from thin walled 1.5" wide PVC piping (I believe it was originally a drain pipe for a sink) and can hold 16 Burger King Straws (1/4 ounce capacity) snugly. I wrap the potion tag around the center of a Q-tip and place said item into the straw. The cotton helps to keep it in position however over time they will slowly move down the straw. That's why I leave both ends of the tube open so that I can simply blow in the bottom end of it and it will shoot up the sinking potions. Interesting note, if you blow hard enough, you can 'dart' a target with a dozen cure light wounds potions - not that it will do anything to help them - but it is funny watching the target's face when you do it
Oh, and the stylin' fabric is that it's my gypsy character that uses it but any cover can be used really.
I usually only keep cure light damage elixirs in it as it could be a little bit difficult figuring out which is which (I suppose you could color code the Q-tips) but the idea behind the design is that you'd have a single container with multiple doses of the same potion
I then took the concept a step further and created the Artisan's Combat Rod.
I found the longest sink drain pipe in the store and used that. It was more or less the perfect size with end lips on it to help with my ideas.
It has two sets of 16 straws, is roughly 18" overall and can hold 4 sets of scrolls on it. The scrolls are held on via some rubber gaskets I found (to keep the whole thing styling). The idea is that you touch the packet, cast the spell, tear off the scroll and repeat with the next one under it. My usual setup (as I often play the support character) is cure light damage potions in one end, Magic Armor potions in the other, and then Awaken, Release, Shield and Dragon's Breath scrolls attached - well an Artisan has to have SOME fun
