For some dumb reason women's wallets tend to be large and bulky.  This wallet is soft leather and fits into even my smallest purses!
Sometimes when I run into a store I like to just grab my wallet and stick it into my pocket and not bother lugging my purse around.
I just keep my essential IDs, one credit card, and one debit card in my wallet.  ALL of my other various discount cards, membership cards etc.-- I keep in my locked car and only take one out when I occasionally actually need to use it.
