Haha that's actually funny. It's not surprising that this promo is over because it's quite easy and cheap to make small tattoo as these ones, and if 0.1 is worth 1000$ right now, it might be worth 10000$ in few months... Really great offer though.
It was fun for those who like tattoo art, but for some people who do not like it then it was not fun at all. I have to admit they did a crazy promo, but I do not think it is a good way of advertising because the tattoo is not visible anywhere anytime.
I have a friend who like this art, too bad I missed this promo. If I did not miss it, perhaps I could ask my friend to make a nitrogen tattoo on part of his body then we can split the prize LOL.
