Every millimeter is measured, every stitch is waxed, and every edge is burnished by hand.
Measures 8 mm empty and 12.4 mm with 8 cards and 6 bills. It fits in your front pocket so you stop sitting on a wedge.
Push your daily card up through the oval exterior slot with one thumb. You can tap and pay without opening the wallet.
A copper-nickel weave runs through the entire lining and keeps contactless cards, passports, and enhanced IDs quiet.
1.1 mm skived full-grain panels, 7-SPI waxed stitching, and burnished edges. No bonded leather, no paint, no peeling.
Your daily payment card lives in the exterior sleeve. One thumb push through the oval cutout lifts it about 20 mm clear, ready to tap or hand over.
Open it flat to find tiered leather card slots on one side, a thumb-cut ID window on the other, and a full-length bill pocket that takes US bills flat.
With 8 cards and 6 bills inside, the SlimFold closes to 12.4 mm. The RFID shield stays unbroken around your remaining cards.

Materials & Build: Cut from 1.1 mm skived, drum-dyed full-grain cowhide and stitched at 7 stitches per inch with waxed bonded nylon thread. Edges are hand-burnished and sealed, not painted, so they won't flake. Slot lips are folded leather with no raw cardboard backing.
Capacity & Fit: Holds 6 to 10 cards plus up to 10 flat bills. The 110 × 82 mm footprint takes US $1 to $100 bills completely flat with about 8 mm of top clearance. Slots are snug for the first 5 to 7 days, then mold to your card stack.
RFID Protection: A copper-nickel weave lines the full interior and blocks 13.56 MHz contactless reads from credit and debit cards, passports, and enhanced IDs. The exterior thumb slot sits outside the shield, so your daily card is ready to tap while the rest stay protected.

The full-length cash pocket takes US bills without folding, with room to spare at the top. No crumpled corners.
The window has a center thumb cutout, so your license slides out with one finger at TSA, bars, and hotel check-ins.
At 54 grams and 8 mm thin, it disappears in chinos, jeans, and suit trousers without wrecking the line of the pants.

Slide your everyday cards into the tiered leather slots and drop your bills flat into the full-length cash pocket.
Put your main tap-to-pay card in the exterior thumb slot and your driver's license in the ID window.
Close it, slide it into your front pocket, and head out. No bulge, and nothing to sit on.
Transferred 8 cards and 6 bills out of my old department-store leather brick and literally patted my front jeans pocket twice in the grocery parking lot thinking I dropped it. Cut the thickness more than in half overnight. Easily the cleanest upgrade I've made all year.
The outside thumb-push slot is the feature I didn't realize I needed until day one. One quick push with my thumb at the gas pump or coffee counter and my primary Visa slides right out without opening the bifold or flashing cash. Tested the RFID shield at self-checkout too—dead silent until you slide the card out.
I fell for the rigid metal plate wallet trend for six months—it wore a rectangular hole right through two pairs of J.Crew chinos and folding dollar bills into thirds drove me nuts. Switched to the Cosari SlimFold and it smells like an actual saddle shop. Snug for the first three days, then molded to my cards like a broken-in baseball glove.
My PT told me sitting on my fat old wallet during my 45-minute commute was tilting my pelvis. Moved everything into this SlimFold and slid it into my front right pocket. Within a week my lower-back stiffness on the drive home was completely gone, and I barely feel it in my pocket.
Bought this for my husband because his old department-store wallet was shedding black faux-leather flakes everywhere. He swapped all his cards over in two minutes, loved how flat US bills sit inside without crumpling at the top edge, and immediately asked me to grab a second one at 50% off for his dad.
Paid $95 for a big-name minimalist wallet two years ago and the painted rubber edge coating peeled off in strips. The Cosari has dense cowhide, tight waxed stitching, and an actual thumb-cut ID window for less than half what I paid before.
Wore this in the front pocket of lightweight wool dress slacks at an outdoor wedding last weekend and it didn't ruin the drape of the pants at all. No clunky metal money-clip bar digging into your leg and no plastic pop-up lever to jam.
After three weeks of daily carry the leather softened nicely around 7 cards and 5 bills, so I did an upside-down shake test over my bed—not a single card budged a millimeter. Smooth thumb draw when you want it, rock-solid hold when you don't.
Don't panic on day one when the card slots feel tight—that's how real unsplit full-grain cowhide behaves before it relaxes. By day four it settled right in and stays whisper-thin in athletic shorts and jeans alike.
So many slim wallets are cut to weird dimensions where US twenties stick out the top or bunch up in the fold. Bills slide straight down into this sleeve with clearance to spare, and moving to front-pocket carry saved my hip on subway seats.

Yes. The full-length cash pocket takes US $1 to $100 bills completely flat, with about 8 mm of clearance at the top. Euros and Canadian notes fit too.
Yes. It's 100% drum-dyed full-grain cowhide with burnished edges. It darkens and softens with use and won't peel the way bonded or PU leather does.
It's designed for 6 to 10 cards plus up to 10 flat bills while staying slim enough for a front pocket. Our test load of 8 cards and 6 bills measured 12.4 mm.
It blocks 13.56 MHz signals used by contactless credit and debit cards, passports, and enhanced IDs. Older 125 kHz office proximity badges work on a different frequency and aren't affected.
Push your card about 15 mm up through the exterior thumb slot and it clears the shield, ready to tap. Slide it back down and it's covered again.
Yes. At 110 × 82 × 8 mm unloaded, it fits front pockets in jeans, chinos, and suit trousers without corners poking through.
