Handmade Leather Magnum Opus 12 Slots Hard Pen Case with Removable Pen Tray


Undyed Leather - Not covered
Undyed leather essentially means nude leather, with nothing covered up. This produces a natural looking product that will have some natural marks, scars and other blemishes. In other words, it has not been processed to make the leather appear perfect, like something you would get in a department store. When you get your brand new undyed, vegetable-tanned leather goods, you are seeing its natural color. The hide is effectively naked and so will age and darken with the sun just like your own skin. Aging will develop a rich color and patina. Sun exposure, daily handling, water, and conditioning give natural vegetable tanned leather a rustic look over time.

  • 100% vegetable tanned leather
  • Hand-stitched using waxed polyamide thread
  • The edges are beveled, waxed, and burnished for a finished look

    The Gold Standard for Pen Storage

    This design is as close to perfect as pen storage can be. Easily transportable, classy and sturdily made. They help keep my precious pens organized and safe. I had some metal money clips that I’d saved over the years to label them which makes finding any particular pen a snap rather than a desperate hunt!

    This is my third Opus 6

    This is my third Opus 6 for my Nakayas and I am very happy for the purchase. Opus is lightweight and carefully designed and engineered, the inner cloth provides a spacious pocket and good protection to my urushi fountain pens. I have also purchased the leather wax this time and after applying on the leather looks gorgeous.

    Galen Leather “Magnum Opus” cases protect your precious pens quite beautifully. Obviously I have a ‘thing’ for fountain pens. I organized them with clip-on tags made from promotional money clips acquired over time, and adhesive labels. They hold almost all my fountain pens except for some odd sizes. The quality is excellent and helps prevent life from slipping into chaos.

    I bought 3 colors.

    12-slots Crazy Horse Brown Leather Pen Pouch

    This pen pouch looked so appealing and tempting I couldn't resist from giving it a shot. And now that I'm holding it in my hands, I can say how pleased I am with this purchase. The material feels so softy and consistent at the same time, the pouch sleeve has a metal plate within it that holds it firmly on the spot. Inside, I can place up to 12 of my favorite pens, so that I'm sure they will be kept safe and in order, ready for everyday use. To be honest, I thought the pouch was a little smaller, and I'm really surprised with the item size and shape. I'm planning to buy a couple more in the future, perhaps pen pouches with different colors to make my room even more colorful and lively. I strongly recommend this purchase, especially considering that each pouch is completely hand crafted and thus original, a true masterpiece on its own.

    Royce (Chiyoda-ku, JP)
    No surprise

    Already having two of 5 pens pouches and wanted to have larger one. The color is decent and quality very satisfying. Always no surprise at the high standards and timely delivery.

    Leather Magnum Opus 6 Slots Hard Pen Case with Removable Pen Tray - Undyed Leather

    The leather is also solid and the construction is also good.
    The fountain pen I have can be stored without any problems.

    Great product

    a classic: functioanl, durable, sensible, beautiful

    The Magnum Opus was an answer to my long years of looking for the right pen case. Durable, without rubber-snug bands which can scatch against the pens, and easy access to all the pens when needed. Magnum Opus has all the requirements, in beautiful hardened leather, in 12 or 6 slot versions and several colors to chose from. This has been my go-to, and each case is a timeline for me, helping track years and fountain pens preferences during that time.
    Since, there have been some similar attempted cases, but none does it quite like Galen Leathers, which is why I insist on the Magnum Opus. I love it!
