I am debating between a penBBS456 and a WingSung 699. I’m leaning towards the 456.

 

I got a couple of the Wing Sung 3013s. They work fine, but they are super cheap. My one gripe is that when you screw the plunger down, they don't seal. They are definitely not in the same category as the Vac700r.

Anyone else have this problem? I put it in and it stays, but moment I try to draw up ink, the plunger come off the stem. Any ideas on a fix? Should I glue it on?

A pain in the (bleep). I love the pen, but experience the exactly same issue, even having the plunger changed. Getting tired of it.

I packed it in. Got a penbbs 456 instead. No problems since. I do not think I’ll be returning to TWSBI anytime soon.

I do. Such a shame.

Yep. In both my 580 and Eco.

I'm sitting here in front of my Eco with a stem in my hand and a plunger stuck down deep in the barrel. Can't reconnect them and even my fancy dental tools can't budge the plunger. Please don't scold me for lack of maintenance. This pen has only been filled three times and when filled it's been an everyday carry. I have two 580s as well and they've worked fine. If the key to keeping an Eco functional is dismantling it and greasing it every time one cleans it or fills it then it seems to me it's a product not ready for prime time at any price.

I have three TWSBI's, 540, 580, and mini. All have had various cracks and the two larger ones have had frozen pistons that have come off of the piston rod, several times each. I removed the section and the piston assembly each time and used a straightened large sized paper clip inserted into the opening in the section end of the barrel to push the rubber piston out of the barrel through the open piston end. Ample silicon greasing has restored the piston's functionality. Until the next failure.

Has anyone tried thoroughly cleaning and degreasing the rod around where the seal seats, and the inner ring of the seal?

I've done this on a 580/mini and I did it on my Vac700(until I did the dumb and dropped the seal down the sink) and it seems to cure this, at least for a long period of time

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
