What I discovered is that this case works great with just three pens, but if you try to fill all the slots, you run the risk of the pens scratching each other since the leather flaps don't fully cover them. Worse, you can't completely close the case. While I realize that leather can stretch, I doubt it can stretch enough to make the case useable for me—and who wants to risk using their pens to stretch out the leather? Perhaps Galen could use some elastic along the zippered portion that would allow the case to expand to accommodate six regular-size pens. I'm not sure. But, in all honesty, I feel uncomfortable putting more than three pens in this case, which obviously means it's no longer a six-pen case.
That said, I looked at the reviews of the six-pen case on Galen's website, and most people were quite happy with it. One or two said that the case doesn't accommodate larger pens, but no one discussed the case not closing properly. Maybe those reviewers use smaller-sized pens. I will probably return my six-pen case and purchase a version that has pen slots on one side only.
Even though this six-pen case didn’t work for me, if you use smaller pens (I’d say pens equivalent to Pelikan M400 size), it should work well for you. The craftsmanship is truly exquisite--there’s no doubt in my mind about that. The case is reasonably priced at $45.00, and you can have it personalized for $10.00 more.
