Bubbles In Plastic?

Hi guys,

I recently purchased a TWSBI 580al and it is great.

 

I inked it up and I noticed that there are few clear "bubbles" along the barrel.

They are fixed, that is, they don't vanish if I shake the ink in the pen.

I am wondering if they are air bubbles within the plastic or something else.

 

What do you think?

Not a big deal, just curious.

Do they stay put when the plunger moves past them?

 

Well, I thought about that. I'll check careful once I run out of ink.

If they move, there's something in the inner surface of the barrel and I can probably remove it by flushing the pen more carefully (maybe it's just silicone grease?).

If they don't move... they are bubbles within the plastic and there's nothing I can do.

I'll post the outcome...

I have a similar thing with Diamine Registrar's.

Strongly suggest that Iron-Galls should go with converter, last time I fill them in my ECO, and found my pen almost ruined by it.

It takes time to use 2ml of ink on an extrafine nib!

Anyway, even though I did not run out of ink yet, I believe it is some residue on in the inner surface of the barrel because the "bubbles" got colored with the ink color.

I have a TWSBI Diamond 580 in Red. The bubble is between the threads on the plunger and the plunger itself. It's just below the threads. It's possibly a bit of silicone, but I am not going to take the pen apart just to find out if that is true.

Peace and Understanding

Yes, I found the silicone dots to be distracting, but I haven't seen any bubbles in the plastic, and I own a bunch of TWSBIs.

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

      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
