Mini-wallet is upgrade of Ziploc snack bag

Small and translucent, rigid and smooth, the Jimi is “the wallet for people who hate wallets,” says Mike O’Neill, the San Francisco cyclist and entrepreneur who founded Mr. Smith Inc.

The slim and unobtrusive case holds credit cards, driver’s license and some cash. It’s made in the USA of recycled polypropylene. It’s 4.25 inches high by 2.6 inches wide, just slightly taller and wider than a credit card.

The case is a clamshell design, opening on integrated plastic hinges, which the company says will survive a million opens and closes. Inside is a slot for four credit cards on one side and a money clip on the other side — just the essentials.

The removable polycarbonate money clip holds a single card and three double-folded bills. The money clip can be snapped out of the case for those trips where only cash is needed.

Though not waterproof, the Jimi ( www.thejimi.com) clicks shut and shelters important stuff from moisture. O’Neill developed the un-wallet to stash in his bike jersey while riding.

“If you get a bit frisky and sweat through your shirt, your cash will not get soggy,” he said.

Available in nine colors, from clear to a deep ruby red, the Jimi costs $14.95. It is about 9/16 of an inch thick and strong enough to withstand the abuse a wallet might typically take.

But while you can put it in your back pocket, O’Neill recommends keeping the Jimi up front in a hip pocket. A lanyard hole allows it to be strung around your neck if desired.

For me, the case limits the clutter you can collect.

“Think of the Jimi as a more robust version of the ubiquitous snack-sized Ziploc bag,” O’Neill said.
