Sonnenleder Pencil Case "Grass" black

The "Grass" writing case from Sonnenleder is a handcrafted pencil case made from purely plant-tanned bovine leather of South German origin. The warm mocha brown, the subtle leather scent, and the lively, natural surface make it distinctive from the first touch. Inside, a fountain pen and two additional pens up to 14 cm in length, as well as flat items, find a secure place – completely leather-lined and closed with a polished metal zipper.

Special Features

• Leather-covered rubber loops: Three elastic loops hold fountain pens and pens firmly in place. An additional leather cover over the loops protects writing instruments from pressure marks and scratches – ideal for lacquered or laminated fountain pens.
• Leather compartment for flat items: A separate leather pocket accommodates a ruler up to 14 cm in length, stamps, or small cards – practical for those who use their case as a compact writing center.
• Leather lining: No textiles or synthetics inside either – the lining is leather. The surface has a pleasant grip without scratching writing instruments.
• Polished metal zipper: The closure runs smoothly and securely, keeps the case completely closed, and reliably protects the pens – even in your bag.
• Traditional pit tanning: The leather is tanned purely vegetable in a pit – a process that preserves the skin's natural character, lively surface, and distinctive scent. No chrome, no synthetic tanning agents.
• Living patina: Rain, sun, and heat change the surface over time. The leather darkens unevenly and develops an individual patina – each case becomes a unique piece.
• Pure handcraftsmanship from Germany: Each case is made entirely by hand. Materials and workmanship have traceable origins: selected South German cattle hides, tanned and processed in Germany.

Application & Tips

• Fountain pens and ink pens: The case is designed for writing instruments up to 14 cm in length – corresponding to common pocket fountain pens, ballpoint pens, and fine-liner formats. Wider fountain pens with large clips fit thanks to the leather-covered loops without pressure marks.
• On-the-go writing set: With a fountain pen, a pencil, and an ink roller plus a small ruler or stamps in the leather compartment, the case is a compact set for desk and travel bag.
• Shape leather patina actively: Those who carry the case regularly from the start and occasionally expose it to light and slight moisture will accelerate patination. The result is a surface that shows your own usage history.
• Care: Plant-tanned leather needs little – occasional re-oiling with an undyed, wax-based leather care product is sufficient. Strong cleaning or waterproofing agents should be avoided as they alter the lively surface.
• As a gift: The case comes without unnecessary packaging and appeals to people who choose writing tools consciously – an object with genuine material character rather than mass-produced goods.

For Leather Enthusiasts

The pit tanning that Sonnenleder uses for this case is the slowest and most labor-intensive plant-based tanning process: the hides pass through several tanning pits in succession with increasing tannin concentration – a process that takes months and gives the leather a particularly dense, firm structure with a high tannin content. The result is a leather that absorbs moisture differently than chrome-tanned leather: it darkens locally when wet but dries lighter again – visible in every raindrop pattern that works its way into the patina over time. The South German cattle hides are renowned as raw material with particularly uniform fiber structure; the combination of origin, tanning process, and manual workmanship explains the velvety, firm feel that distinctly differs from calendered or chrome-tanned leather. Color and structure variations between individual specimens are not defects but rather an expression of the natural surface – each hide brings its own grain pattern.
