The tube almost looks like the empty ones you get from heartfelt for putting beads into. I have 3 tubes with beads in my traveldor.

latenightcigars, for a small humi one of those 1/2 oz tubes would probably be enough. If you want to get specific there is a "calculator" on the heartfelt website that will tell you exactly how many beads you need for your humi.
