As of right now, looking at my writing desk, I own around 8 pencil cases, (this is excluding ones strictly for fountain pens) and tend to cycle through them. Some are better if I'm not carrying much, the lovely one that CW Pencils gave away for buying a bunch of stuff holds a special place in my heart (and I sewed on my Pencil of the Month Club badge on it), and some can hold everything but the kitchen sink.
However, there's a difficult child that we all love in the world of pencils, and that child's name is the Palomino Blackwing. Any person who really likes pencils has at least a few of these, and for good reason. However, an unsharpened, or even recently sharpened Blackwing comes in at a whopping 7.9 inches. It's huge compared to other pencils. Many "pencil cases" can only hold a max of a 7 inch pencil, (some even less than that). My CW pencil pouch can hold them, but if you want to have them be organized (and not have to carry around a monstrously huge pencil wrap), you haven't had many options.
I was at Kinokinuya (an amazing Japanese bookstore/stationery shop in NYC) a few weeks ago, and while looking at their pencil cases, I found a case that I had never seen before, the Raymay Topliner. It was large while not being obnoxious, had individual slots per pencil, and seemed svelte considering it's length. I compared it to an unsharpened Blackwing, and showed my wife with the excitement of a 3rd grader. (I think she just nodded and said "Cool" in that way that says "Fred I have no idea why you are so excited but sure, I'll play along".) So it could hold some Blackwings, but how is it as a pencil case?
Storage, and then some.
The design of the Topliner is simple and practical. It's polyester (yet softer than most polyester pencil cases, which I like), with 2 very smooth zippers keeping it closed. On the opposite side of the lid is a small pouch for maybe a ruler or something, but it's not a pouch I used (and I didn't even take a photo of it). On the insider is a top pouch, for leads, erasers, or what have you, and then a removable tray which can hold 5 normal width pens or pencils in elastic loops, and then a loop that is about 3 times larger than the others. I tend to use this one for my Pentel Multi pencil, but it can also work for some portable scissors, a Sharpie marker, if one of your fingers are removable. You have options.
If you either lift or remove the top tray (which is held in with Velcro), underneath you have a nice storage area for erasers, smaller sharpeners, highlighters, etc. The depth of this compartment is only about 3/4 of an inch, and doesn't really have a lot of space for more (due to the top tray sitting on top). The normal Kum Autopoint sharpeners stick out like a sore thumb, along with ones from T'Gaal and Ratchetta. Fortunately, there's enough space to fit the Kum Masterpiece in there, even with it's plastic case. As you can see you can also fit the Dux Brass sharpener fits happily as well.
As long as you don't try to fit anything huge underneath, you'll be fine.
A very nice removable tray to held our precious Blackwings.
In terms of toughness, this case has been a constant companion the last few weeks. I throw it in my backpack which also has notebooks, a 15" Macbook Pro, and sometimes a jacket or hat, which takes multiple trains each day. I haven't had any sort of issue on things being shifted (in terms of the pencils in the elastic loops), or things getting crushed. There is plastic built into the sides, as well as on the top, bottom, and middle tray, which gives it some ridgity. I think this case will be able to withstand some decent punishment (though I wouldn't run over it with a car).
Is this the end of me buying pencil cases? Probably not. Pencil cases are fun, and I like switching things up fairly often. However, it's nice to know that I now own a pencil case that can hold one of my favorite pencil brands without feeling like I'm going to stretch out the fabric too far or have the pencil sitting at a funky angle to get it in. For the prupose of carry Blackwings, this is the ultimate pencil case, and I highly recommend getting one.
