Sonnenleder Pencil Case "Richter" mocha brown

The Sonnenleder pen case "Richter" in mocha brown is a three-part pen pouch crafted from vegetable-tanned bovine leather, made entirely by hand in Germany. The leather comes from selected South German hides and is tanned in a pit using pure plant extracts – a slow, traditional method that gives the material a vibrant, breathable surface. The result is a pen case that feels warm and supple from the very first moment and carries the characteristic, authentic scent of natural leather.

Features

• Vegetable pit tanning: In this traditional method, leather rests for months in tanning baths made from plant extracts. The result is leather with a lively grain structure that regulates moisture and develops a unique patina over time – shaped by rain, warmth and light.
• South German bovine hides: Selecting raw hides from the region ensures an even, dense fibre structure. The leather is hardwearing without appearing stiff.
• Leather lining: The inside of the case is completely lined with leather – no synthetic film, no textile. This protects delicate lacquered fountain pens and polished pens from scratches and doesn't absorb ink.
• Three rubber loops: Two wider loops for fountain pens up to 14 cm long, one narrower loop for slim pens or refills. The rubber loops hold even heavier fountain pens securely in place without pinching the barrel.
• Quality zip closure: The all-round zip fastener closes the case completely – no pen can slip out, and ink stains on other surfaces are a thing of the past.
• Pure handcraft: Each case is sewn and inspected individually. The careful edge finishing and even stitching are visible hallmarks of this handmade production.
• Living patina: With each month of use, the case's surface transforms – colour depth, shine and feel develop individually. No two cases look the same after a year of use.

Use & Tips

• Daily desk companion: Three pens cover most writing situations: a fountain pen with a standard nib for flowing text, a stub nib for headings or calligraphy, a pencil or ink roller for sketches. The case keeps this selection compact and together.
• On the go: The zip format makes the case travel-friendly – it can fit into any bag without the nib or clip catching on other items. Fountain pens with piston fillers or converters sit safely in the loop.
• Calligraphy setup: Those working with stub nibs and spare nibs can keep one nib in the case and use the second loop for an unmounted nib holder – provided it's under 14 cm long.
• Leather care: Vegetable-tanned leather absorbs leather conditioner well. Applying a thin, colourless leather conditioner every few months keeps the surface supple and deepens the colour. Dab strong moisture briefly; don't rub – the leather dries on its own and retains its shape.
• Breaking in: Initially, the rubber loops may sit slightly snug. After short use, they adapt to the diameter of the pens you use regularly.

For Leather Enthusiasts

The pit tanning that Sonnenleder uses for the "Richter" pen case is the oldest known leather production method – and the slowest. Unlike chrome tanning, where leather is finished in a few hours, bovine leather in pit tanning spends months in extracts from oak or spruce bark. The result is so-called full-grain leather with an intact surface: the natural pore and grain structure remains visible and active, the leather responds to moisture and temperature. This very responsiveness is why the patina becomes so vibrant – mocha brown deepens with use into a rich, almost honey-coloured brown at the edges and grip zones, while the flat surface becomes more even and smooth. Each piece is thus unique, carrying its history in the surface.
