Although guys don't carry a purse,
I do have a wallet that's been with me for a good seven to eight years now. I carry it wherever I go, regardless of the occasion or the clothes I'm wearing. My relatives have given me various wallets over the years for birthdays or holidays, but I still use this one, not because it's my favorite, but it's the ONLY wallet I care to use.
This one is a black leather wallet, 4" x 7" (folded), and has various card holder pockets. I also like a wallet that has plenty of space to hold spare change - because I tend to end up with a ton of coins.
Here's an inventory of what's inside:

Here's an inventory of what's inside:
- Some small bills and change
- California Driver's License
- Bank Of America Visa Debit Card (as good as dead)
- Citibank MasterCard Debit Card
- Borders Membership/Discount Card
- GameStop Card
- Smart & Final Discount Card
- AllState Proof of Auto Insurance
- Social Security Card (Oh, my, I should leave that at home)
- Kaiser Permanente Medical Card
- Wells Fargo Visa Corporate Purchase Card (I don't know why I carry this with me; I use it only for work/department-related transactions)
