Sonnenleder Pencil Case "Busch" mocca brown

The Sonnenleder "Busch" pencil case is a flat, slim leather pouch crafted from vegetably-tanned cow leather in a warm mocha-brown tone. The leather is hand-processed in Germany – free from chromium salts, tanned with plant-based tannins from bark, roots and fruits. The interior is lined with soft suede, and it closes with a metal zip.

Features

• Vegetably-tanned cow leather, hand-processed in Germany: Tanned without chromium using natural plant-based tannins. The leather retains its open-pore structure, is breathable and develops a unique patina over time – every discolouration, fingerprint and light mark becomes part of its character, making each piece truly one-of-a-kind.
• Suede lining: The interior of soft suede is velvety-smooth and protects writing instruments from scratches – ideal for fountain pens with delicate nibs or lacquered surfaces.
• Metal zip: Runs smoothly and evenly, securely closes the main compartment. No bending, no popping open when carried in a bag.
• Flat format 19.5 × 10.0 × 1.0 cm: Slim enough for a jacket pocket or backpack inner pocket – fits alongside an A5 notebook without bulk.
• Mocha-brown: A warm, mid-tone brown with subtle earthiness – neither too pale for heavy use nor too dark for light desk surfaces. The colour continues to develop with the leather over the years.

Use & Tips

• Daily companion for 2–4 writing instruments: The main compartment comfortably holds several fountain pens or fine-tip pens side-by-side – without them striking each other.
• Care: Vegetably-tanned leather should not be sealed or waterproofed – the open-pore surface is part of its character. During dry spells, a neutral, oil-free leather conditioner that doesn't alter the colour will help.
• Breaking it in: Fresh from production, the leather is slightly stiff. With regular use it becomes more supple and fits snugly around your pens.
• Zip maintenance: A light touch of beeswax along the metal teeth occasionally keeps the mechanism smooth long-term.
• Engravable: Vegetably-tanned leather accepts laser engraving and hot-stamping particularly cleanly – the pouch makes an ideal personal gift with initials or a monogram.

For Leather Enthusiasts

Sonnenleder works exclusively with South German cow hides that are vegetably-tanned using plant-based tannins from bark, roots and fruits. This process completely eliminates chromium salts and keeps the leather free from harmful substances. The result: an open-pore, breathable structure with a rich feel and characteristic leather scent. Natural scars, growth lines and subtle colour variations in the hide are not concealed – they prove the material's authenticity and distinguish each piece. The patina that forms over months and years densifies the surface and makes the leather increasingly resistant to moisture.
