They are absolutely addictive. Every friend of mine who has been inked is either in the process of or planning a sleeve. I got my first "moto tat" when I was in the military. Thankfully, it was the only military-related tat I ever got. In roughly a two-year period, I spent well over $2,000 on ink; ending up with two major pieces on my back, left arm sleeve, 3 on my right arm, one on my chest, and one on my ribs. My right arm is mostly tribal, but I am hoping to sleeve the entire thing and make it look less like a tribal design. Several are Norse runes or symbols relevant to war and battle.
