Fluctus is a long wallet with a slim, clean silhouette and a thoughtfully organised interior. Its name comes from the Latin word for wave, echoed in the curved stitching inside. Two large pockets offer room for your smartphone, notes and receipts, while ten card slots and a zipped inner pocket keep every essential in its place. A leather tab closure and the mini Hiva logo in metal on the front complete the look. It slips easily into any bag, or can be carried on its own as a small clutch.
