My name is bleach, I am a tattoo artist at saint sabrinas in minneapolis. I am borderlined obsessive compulsive, so a friend and coworker of mine thought this would be a good idea for my knuckles. I thought it would be a good idea to mess the letters up and not have them perfectly straight. So here’s what we came up with.

Hello all,

In my wanderings around Austin this week (or so) I picked up a few pictures of people’s knuckle tattoos. Check them out:

Elizabeth sends us these knuckle tattoos, showing just how hard core she is, sorta:

I was watching SNATCH one day and said to myself how I loved the british gangsters in that movie…then it hit me that it would look good on my knuckles. Simple story. It is such a popular term in pop culture, but I really didn’t mean it like “oh I’m gangsta”…it was really about actual dim witted gangsters that can’t do anything right. Similar to myself…lol

Allen Carlson sends use these knuckle tattoos:

i got them after i moved out and realized alot about who my friends are and how much my family means to be..
and you really have to be devoted to what you love and do and who your friend and family are and my religious beliefs had a part to do it with..
plus i wanted to get something different that i had never seen someone with before
