I ordered the PenBBS 456 Vacuum Filling Smog 54 RM at the same time I ordered the PenBBS 500, because I was intrigued by the filling system, and I wanted a PenBBS 500 with the Smog design but there weren’t any available. I was expecting to like the PenBBS 500 more because from the pictures it seems to have a more classic design, but the PenBBS 456 is the perfect example of how pen pictures often misleading.

The 456 is a much sleeker pen than its chubby 500 counterpart. There’s also significantly less hardware on the 456, which makes it both lighter and better looking. Massive chrome details on fountain pens just seem to cheaper their look in my eyes. If the cap band had been about half the size then the 456’s design would be better, but as it is it’s not a pen that I’d be ashamed to carry, and it looks more expensive than it actually is.

The steel nib on this is a medium, and it writes at about a 0.7mm line, as described. The nib design itself is elegant and clever, with a calligraphy “M” designating its width. The nib itself is smooth with some feedback, and has little or no give.

I purposefully filled this pen only about a third of the way up once I realized what a massive ink capacity it has. The filling mechanism is somewhat elaborate, like all vacuum fillers, but it works, and unlike the end-cap on the PenBBS 500, the PenBBS 456’s end-cap doesn’t twist off unintentionally.

The smog material is really beautiful, and it’s a way to get some of that Visconti vacuum-filler, London Fog feel without breaking the bank. This pen proves that you don’t have to pay hundreds and hundreds of dollars to have a nice pen that you enjoy writing with.

Some more closeups on the overly large cap band (if only it had ended on the line below the “Shanghai”) and the lovely smog material. You can also see the filling mechanism clearly:

The material looks even better when the pen is filled up with ink, but I just wasn’t willing to dump out so much ink, and I knew that I would be forced to do that if I topped the pen up:

Pilot Iroshizuku Fuyu Syogun was one of the first Pilot Iroshizuku inks that I splurged on. It shades beautifully, and is a lovely cool (i.e. bluish) grey that is utterly not waterproof, and so can be “stretched” and reworked as you can see in the small sketch that I did:

This was drawn on Tomoe River paper, but you’ll see shading on Rhodia and Clairefontaine paper as well. Of all the grey inks I own, this one is still my favourite. It’s dark enough to be readable (and appropriate for office use), and offers a lot of interest and drawing potential with its shading.

Like all pens that aren’t cartridge converters, cleaning this pen out will take a bit of effort, and vacuum filling pens are more difficult to clean out than piston fillers or lever fillers (only button fillers are worse IMHO). It just means that you’ll need to have patience when filling and cleaning this pen out, and that you probably shouldn’t put shimmering inks or inks that are difficult to clean out (or stain the pen body) in a pen like this. Then again, the pen costs $32, so if worst comes to worst, you haven’t ruined an expensive pen.

I wish that PenBBS would pick a naming convention that is easier to remember than the one it is currently using. But other than that and the not great cap band, for double the price the PenBBS would still be a great buy.
