Pull Tab

Love this design with minor an imperfection for me. It has no pull tab to assist the slide-out tray so, I added my own Ultra-Suede tab. By no means is this a deal-breaker as I will purchase another soon. I am a huge fan of Galen products, from the excellent craftsmanship to superb materials used no one comes even close.

Magnum Opus 6 - Crazy Horse Smoky

It is so beautiful. The colour is gorgeous.Beautiful and practical. My pens will be safe there. I am very satisfied.

Margaret Dunlap (Sacramento, US)
Perfect & Beautiful!

I am proud and blessed to be the owner of several Galen Leather products. I fell in love with the case the moment I saw it. I debated over the 6-pen vs 12-pen case thinking the 12 might be too large. I opted for the 12-pen case as I have the pens to fill it. I was pleasantly surprised that it isn’t large & is actually quite portable.

Wonderful case

I have purchased other cases from Galen Leather and was always happy with the quality of their product. The black 6 pens leather case is one of their best. Elegant, sturdy, and easy to use. It is capacious and can house even some of the largest pens like my ASC Bologna collection or the Visconti Salvador Dali or Declaration of Independence. It is solid and guarantees protection and the sliding pocket allows easy access to any size pen. It is perfect for those who like to carry several inked pens/pencils with no worry of scratching them. It also presents very well in any setting and is pleasant to the touch. Highly recommended!

I like this color

Good color and good quality. I filled it with my favorite pens.

Desktop perfection

It is even better than it looks online. I have it filled with all of my Sailors.

Carol Smith (Eugene, US)
Beautiful Case

I like that this case has individual slots instead of elastic bands like so many other cases, so my pens can never touch each other. It easily holds even my longest pen - an Esterbrook Estie (149mm/5.9in). I'm not a fan of fat pens so don't own any, but there's room in the slots for pens chunkier than any of mine. The outer part of the case is heavy and rigid, so my pens are well protected. The magnetic closure is quite strong, no danger of it accidentally coming open. Of course, the workmanship is superb - nice finish, precise stitching. The smooth, light finish shows light scratches and scuffs pretty easily, but I figure that's part of the beauty of leather.

Eric Wee (Suwon, KR)
Best Pen Case Ever Owned

12 slots are enough to hold my favorite pens with sturdy protection from outside. Each slot is large enough for big pens like MontBlanc Meisterstuck 149. Slick black leather feels nice and in good quality. Recommandation!

YS Rhyu (Daegu, KR)
A well made pen case

It seems to be capable of storing almost every fountain pen with soft fabric inside to prevent scratches. The case itself is somewhat vulnerable to scratches but applying Leather Balm from this site makes it harder and darker. I am very pleased about this product and someday get a bigger one.

Brandon (Lafayette, US)
Aptly named. If you think you want this, you do.

I've had a few Galen products over the years, all still working as well as the day i got them. The Magnum Opus (12) is a work of art. I'll keep this short; it's amazing. Buy one.
