Ok, so i'm having a major quandry, here. I use boge cartos, both rubberized and steel cases. I'm hooking two friends up with eGo kits, variety of juices and cartos for xmas, so now I really have to figure out how to effectively and permanently mark cartos/mini bottles with data on whats inside it. I've tried permanent sharpies... wears off and smears on cartos, condoms, and tiny bottles. Nail polish doesn't work, either.. chips right off. What do you guys use to 'label' your stuff? I'm going nuts here, and i've got to come up with some system that works, and ideally looks nice, also. Any ideas? Thanks so much! I've tried so many things, and all i've got is a sticky smeary mess.
