Sonnenleder Wallet "Wienfluss K" natural

The Sonnenleder wallet "Wienfluss K" in natural leather combines a large coin compartment in the style of the classic Viennese box with eight credit card slots and a banknote compartment – all in a compact format of 98 × 95 mm. The cowhide comes from southern Germany and is tanned in Germany using traditional pit tanning methods with purely plant-based tannins: infusions of bark, roots and fruit, without chromium. Each piece displays an individual surface and colour structure – the light brown-reddish natural finish is the untreated result of the tanning process itself.

Features

• Coin compartment in the style of the Viennese box: applied on top, generously sized, with solid press-stud strip – coins can be removed in an organised way without having to open the compartment fully.
• 8 credit card slots: capacity for cards, ID documents and business cards, organised and within easy reach in a slim body.
• 1 banknote compartment: flat and openly accessible, for notes in original size or folded.
• Two press-studs from Germany: solid metal fastenings that keep the wallet securely closed – no zip, no velcro.
• Plant-based pit tanning: The leather is tanned in twelve pits with progressively increasing tannin concentrations over six to twelve weeks – a slow, gentle process that gives the leather strength and breathability.
• Natural finish without surface treatment: The characteristic light brown-reddish colour is not a colour coating, but the natural result of vegetable tanning. Colour and structure variations between pieces are inherent to the process and make each piece unique.
• Patina with use: The leather darkens through contact with light, moisture and hand warmth, initially unevenly, and gradually develops a closed, protective surface – the individual history of use of the piece becomes visible.

Use & Tips

• The wallet is ideal for anyone who wants coins organised and within easy reach: the coin compartment with press-stud strip keeps the contents tidy but opens quickly – practical at the till.
• Natural leather responds to moisture and sunlight with darkening: if you want the patina to develop evenly, carry the wallet consistently in your trouser pocket – body heat gently accelerates the process.
• Occasional conditioning with a colourless, plant-based leather balm is all that's needed for care – no spray, no polish. The leather readily absorbs care products through its open fibre structure.
• The 98 × 95 mm format fits flat into any outer pocket of a jacket or the back pocket of trousers without bulging.
• If giving the wallet as a gift: the leather has a characteristic scent of plant-based tanning – a feature that many leather enthusiasts recognise and appreciate as a mark of quality.

For Leather Enthusiasts

Sonnenleder uses exclusively southern German cowhide and tans using the traditional pit tanning method – a process in which hides are slowly tanned through in several pits with progressively increasing tannin concentration over weeks. This method produces particularly strong, breathable leather with an open fibre structure that readily absorbs care products and becomes more supple with use rather than brittle. The undyed natural leather of the "Wienfluss K" undergoes no additional dyeing or coating process: the surface remains in its raw state after tanning – grippy, slightly rough, with visible grain structure. Locks and press-studs are manufactured in Germany and are part of Sonnenleder's commitment to traceable, short supply chains.
