Sizes & capacity

Every SYLQENN piece is listed here with what it holds, its folded size and the size of its flat blank. Card counts assume standard bank cards (ISO ID-1, 85.6 × 54 mm, 0.76 mm thick).

01 How to read the numbers

Holds — the first number is comfortable, the second is the most the piece takes. Embossed cards count as about one and a half.
Folded — width × height × thickness when closed and empty.
Flat blank — the size of the leather before it is folded, as drawn on the dieline.
New leather is snug. Expect a card holder to take one more card after a few weeks of use.
Notes: “folded once” means a banknote folded in half; “flat-ish” means a note folded once lengthwise into the Folio’s full-length pocket.
