Marcopolini: Campbell-based Marcopolini imports high-quality, hand-made leather goods from Italy, including card cases. I own a Marcopolini key wallet (which, for those who don’t know, is a keychain that stows your keys inside a coin-purse-like wallet, so your keys don’t punch holes in your pockets). It is extremely well made, and its leather keeps looking better as it ages.
Zeyner If the Lucifer from the Rolling Stone’s Sympathy for the Devil carried business cards, he’d carry them in a case made by Baldwin Park-based Zeyner. These double-take-inducing, highly functional cases feature top-quality leather and handmade-jewelry hardware, stitched together by someone who wanted this case to last forever under all circumstances. I do not yet own a Zeyner card case, but my Zeyner briefcase remains one of my most prized possessions.
