Tom Barrington Leather, based in California, makes a wide variety of leather goods and accessories, including pen cases, pen sleeves, wallets, and glasses cases. They were kind enough to send over one of their two-pen sleeves in brown ostrich, and it's one of the nicer leather pen sleeves that I've had the opportunity to review.
This two-pen sleeve looks, feels, and smells like good leather. It's supple, the stitching is tight, and I can't find a visible flaw anywhere on the product. The exterior of the case is made from "fully quilled" ostrich leather - the highest quality. The interior lining is cowhide. The two layers of leather give the case a substantial feel, but at the same time it's still soft and not at all stiff. (On a lot of cheaper leather pen cases, the leather can feel thin and flimsy, or rough and not pliable.)
The Tom Barrington two-pen sleeve easily fits two large pens. Pictured in this review are my Pilot Custom 823 fountain pen (a large pen my most standards) and my Sailor 1911 Black Luster. The sleeve is snug enough to hold your pens securely - they won't be falling out - yet it's not so tight that you can't deploy them easily.
Tom Barrington sells directly through their website, and they also operate an Amazon store with most of their products eligible for Prime delivery. While the ostrich leather case featured in this review is not inexpensive, Tom Barrington offers a range of products at multiple price points. Cow leather sleeves start at $34, Stingray leather starts at $80, and Ostrich at $119. I have a thing for brown crocodile grain leather, so I'm eyeing one of these glasses sleeves next.
Thanks very much to Tom Barrington for sending this over for review, and for sponsoring The Gentleman Stationer!
