Some use them as tool to convey meaningful messages or as "remembrance" of past / present experiences
Than you get the weird ones that i am not sure what they express..
if i wasnt petrified of needles, id get one or two myself...
they are quite sexy i must say, but my major concern is HOW WILL THEY LOOK AFTER 40YEARS?
Only bad thing is, they are permanent..
aint no going back ....lol
