A pencil case is an important accessory if you're going to keep your writing instruments organized and protected from scratches. I have several that can handle various amounts of pens, from two or three to a dozen (although that does stretch the case quite a bit, so I try not to take that many at one time).
This Cplay Sevenroll Leather Pencil Case has been on my "must have" list since they arrived at JetPens, and I finally decided to get one in Sweet Cherry Red. That vibrant color won't be lost in my messenger bag, but there are quite a few to choose from if you want something a bit more subtle.
The case is a roll up with a belt closure that can be loosened to accommodate larger pens. I like that it's not a tie closure, which tend to open up in my bag and spill out all my pens. The stitching looks sturdy, while the various brass pieces (zipper, grommet) are heavy but not overly so. The case is fairly light in weight, in keeping with its soft leather. Scratching may be an issue, we'll have to see how this case handles being in my bag with lots of other items. But it's small enough when rolled and closed that it won't take up much room, so it likely won't get too banged up.
There are four pockets in this case to hold pens and pencils of various sizes, including an Edison Huron and a Waterman Hemisphere pictured above. One really nice feature is the small zippered side pocket for erasers, pencil lead refills, or whatever you want to carry--I like to keep a few dollars in different compartments like this, just in case.
If you're in the market for a new case, do check out this Cplay Sevenroll at JetPens. Definitely a nicely designed and made leather pencil and pen case.
