What wallet do you use?
Title says it all.
Of course, this isn't a watch, pair of shoes, or tie; likely nobody will recognize or care what wallet you have, but it's something you touch every day and should last a while, so it's nice to have a nice one.
What brand? How long have you had it? Is it bifold? Trifold?
And if you don't have a wallet, what do you use instead?
