Anyone have an idea on how to label carts?

I bought a bunch of AA battery cases recently, and although I do use them for batteries, it dawned on me that they have potential for e-cig uses. They're designed to hold 4 AA batts, but they will also hold:

(4) 3ml plastic dripper bottles (such as those used as samplers by vendors) - perfectly.

or

(5) 901 or 510 cartridges - a bit less than perfectly, but with enough stability that they stay in position and don't roll around.

I don't use pre-filled carts, but for those who do, labelling the box with the type of liquid and date may be much easier than labeling each cart.

(You can find the boxes on eBay or Deal Extreme, among other sites.)

I used the white adhesive medical tape that I found in my medicine cabinet. Cut little pieces, used a Sharpie. Labeled V for vanilla, C for chocolate, etc. If I wash or restuff the cart, and as I get new flavors, I just peel off the little square of tape and replace with a new label. Voila! - cheap, easy, fast.

I made an awesome case from a Sony memory stick case, LCH-MA, and on the inside cover I stick a post it with a flavor list depending on the cart slot. As stated before, a craft organizer or pill case labeled also works well if you are refilling several carts/flavors at a time.
