Materials: 17ab Crazy Horse+Suede or Veg.Tan + Polyester

We offer our Magnum Opus in two exceptional leathers, each selected for the way it transforms through use

Option 1: Crazy Horse Leather

Crazy Horse Leather is a type of full-grain leather finished with natural waxes that react beautifully to handling. It’s known for its rugged, velvety surface and the way it proudly displays every mark and scratch as part of its character.

Suede is a luxuriously soft and textured lining that adds a subtle sense of indulgence. It cushions your belongings and offers a premium tactile experience every time you reach inside. Completely safe for your pens

Option 2: Italian Vegetable-Tanned Leather

Italian Vegetable-Tanned Leather is tanned using traditional, chemical-free methods for a firm hand and warm, earthy tone. With use, it darkens and softens gradually, taking on a character that's uniquely yours over time.

Polyester Lining is a durable, low-maintenance fabric built for everyday use. Quick-drying and resilient, it's designed to keep pace with your daily routine. Completely for your pens.
