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


Undyed Leather - Not covered
Un-dyed leather means, nude leather, with nothing covered up - so they will have some natural range marks, scars, and other blemishes. In other words, they are not processed to make them appear perfect, like something you would get in a department store. When you get your brand new un-dyed vegetable-tanned leather good, it looks a 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.

I needed a case for my small but growing fountain pen collection and saw a few reviews of Galen Leather products on YouTube by respected, well-known fountain pen reviewers. They were all very positive, so I decided to give it a try. I went with the smaller 12 slot case instead of the larger 40 pen case because I thought it might be sturdier. It has a slot for every pen, not just an elastic strap. I cannot compare the other, but the 12 slot case is truly very well-made. It is very fine leather and even the "cardboard" case is so nice, I have not thrown it away, but keep the leather case in it. It is not even cardboard, but something in between cardboard and pressed wood, very strong and even beautiful with the Galen logo on it. Everything is high quality. I am writing this review because I am returning to purchase another one. Have not decided on the color yet, maybe blue. Funny thing is I need it for my Frankenpens I hacked together from cheap knockoffs, originally something I did not intend to do because the case is too good for them, but now I believe the case will display the pens in such a way as to "elevate" them in quality too.

reliable and sturdy, Opus Magnus

my go-to sturdy case; perfect size, tough, felt pull-out tray, easy access with magnet closing. I love these, and most of my fountain pens are housed in an Opus Magnus. I generally prefer the black leather, but crazy horse variants are beautiful as they age with usage and time. 💕❤️

The Ferrari of Pen Cases

The 6 pen case in black leather has exceeded my expectations, which were already set very high. From my largest to my smallest, any of the pens in my collection fit within the case. Would highly recommend to anyone looking for a pen case.

Color is nice and easy to use.

beautiful faded blue

the external blue is faded but distinctive, while inner sections shine a stronger blue. I love Magnum Opus cases for their durability and size; perfect!

Great quality, gorgeous dark black colour

I needed a sturdy pen case to keep my humble collection safe on the road.
The leather is absolutely stunning! Such a dark black colour!
I also love the separate tray that makes it easy to display and take out pens, without having to pull them out of a deep pen slot.

Repeat customer for a reason

1st bought 2 of the 12 pen cases couple of months ago based on you tube video reviews. Now have one in every color and am using them exclusively to store my fountain pens because I can store my pens vertically on my bookshelf (critical for inked pens). I have other cases but these are simply the best; thick protective outer leather, sliding lined trays holds pens individually on the inside. The cases are handsome and extremely robust. They hold long pens like my Bexley Holiday windows, & Visconti opera master with ease and fat pens like my Montblanc 149 are easily accommodated as well. Unlike cases with elastic bands these cases will never wear out making them a far wiser choice. The slide out tray makes accessing the pens effortless (just remember to keep the case vertical or close the cover half way so your other pens don’t end up on the floor). I looked at other high end pen cases but none met my needs as well as these cases and at a significantly better price even with shipping. Will definitely buy more of these cases as my collection expands as these are the only cases I will be using for all but my cheapest pencils and ballpoints.

The perfect case for my favorite pens. Leather quality is outstanding. The inclusion of some little extras in my order was very sweet, and appreciated.

beautiful as anticipated / great for black pen enthusiasts

beautiful hard case; I had a set of black (both 6 & 12 pen), but knew i would eventually get the Crazy Horse Smoky Grey. While the black is clean and shiny, Grey has natural streaks of color variance, which will increase over time in a pleasant way.
I imagined how the grey background would contrast nicely against black pens, but actually seeing it for real was immensely satisfying!

Grey/Brown/Orchre/Undyed cases are perfect to keep and demonstrate your black pen collections. Black/Blue/Blue similarly would contrast well for your colorful pen collections, especially if the pens are bright colors.

Thank you Galen Leather! Amazing as usual!

Amad Demetrious (San Anselmo, US)

This is a great case.

The inside has a very nice soft lining to cradle the pens.

Even my very large Omas Grand Paragon, including its clip with the swooping arc, fits. The edges of each slot have a little give.

You can expect their typical quality leather, that lends itself to deepening beauty as patina develops. It's not a slick, designed to look perfect, designer, plasticky grain leather. That's not to say it's lesser quality. I don't believe it is, it's simply designed with a certain comfort and ruggedness in mind. It is very sturdy.

Whether you want to baby it and keep the perfect smooth finish or embrace the patina from being carried about, the case looks beautiful either way.

I appreciate the low profile look and dimensions of the case. It is at home on a bookshelf or tucked discreetly away. It's easy to tuck away.

I like keeping it open while I write if I'm using different pens. It gives my creativity a nudge seeing them at the ready.
