I know this is an older video, but wanted to add that I have multiple TWSBI ecos, with significant shimmer inks in them- still write after not touching for 4-6 months! That cap is amazing!!

TWSBI is one of my favorite fountain pens, and I have a wide range. I have a TWISBI Vac, and it’s been great. If you purchase one, make sure you buy the Vac ink filler (I’ll edit with the exact name later), because it makes ALL the difference. Great video, thank you.

Thanks for sharing your collection!

Two points, both opinions. Your line with differences are almost always to do with the ink. And I believe that gasket is to help grab the cap when posting.

The regular 580 looks huge when posted!

Thanks for the comparison, I was thinking of getting the Rosegold diamond but now that I see how large the pen is posted I will stay with my mint eco! I do love the sound of a TWSBI cap going on and off the pen.

Thanks to you I finally understand why my TWISBI Eco's medium nib drops lines that look disproportionately wide! Since it's new, I've only had one ink in it and that's (take a guess)....yep, Noodler's Lexington Gray! I was hoping for more line variation between my medium and broad nib. Now I know that when I change the ink in the medium nibbed pen the problem will likely be resolved! 🙂👍

It seems like we have a lot of the same tastes! I love fountain pens.

I am left-handed and have had difficulty with fountain pens due to hand position. I have three TWSBI pens with medium, fine and extra-fine nibs, and I love them. I haven’t experienced any issues with writing left-handed.

very nice detailed review. thaks

Hmm I had Schwartz Rose in the same pen with F nib and it got clogged. I had no issue cleaning it, but I tried again a few times and it always ended up clogging :( Too bad, I love shimmery inks in a fine line.

I agree. The nib behaves in a different way according to the ink ; it is also my experience.

The gasket on the back is to keep from over tightening, so it won't affect the use of the pen at all 🙂 I've never posted my 580s, because the cap perches so shallowly I'm not convinced that it's designed to post. 🤷

Do you find the Eco EF to write smoothly? I heard another KZfaqr who said that the F and EF have a fair amount of feedback? Just wondering your experience. Thanks!

I have enjoyed watching your ink swatching and fountain pen videos very much! They could never be to long for me🤗 Have you had to re apply silicone yet to your Twsbi Ecos or any of them? I had the piston stuck inside my pen and had to remove the nib and feed in order to prise it out, scary. I think I might have waited to long before applying the silicon. Now I am having trouble putting it back together properly, the piston knob won't screw all the way down. 🤔 The Twsbi Go and Lamy Safari and Lamy Al, also write beautifully, and they are great to use with shimmer inks as they are really easy to clean😊

How does the Extra Fine nib write, is it scratchy?

A good comparison, but where’s the broad? 🤔😉 I hope the TWSBI broad isn’t a mega wide line as I’’ve got one coming in the Prussian Blue. Thanks!

How odd, I was just looking into replacing my Ecos with Minis and this video was posted. Those Ecos sure are long. Thank you!

Some of the writing width/size will also be determined by the age of your TWSBI. They currently use JoWo nibs. But used to be Bock nibs. Will this be highly drastic? No. But I do know my Bock 1.1 nibs write much wider than the JoWo nibs, no matter the ink choice

Very informative video. I haven’t tried fountain pens...yet. 😁 This was helpful to see and I’m wondering if you could show what’s involved with using and caring for fountain pens. I’m interested in trying them but also afraid I may either become addicted to them or regret the purchase because of the extra work they take. 🤪

Hope you’ll add Vac and Vac mini to your collection !

My Vac Mini works perfectly. I haven’t bought a Mini because the Mini is smaller than the Vac Mini and the Vac Mini holds more ink.

You forgot the I in the last one! 👁

I have only two TWSBI pens now, and ECO, and a Diamond 580 ALS. Both are very good writers, but I'm not fond of piston fill pens, and I hate vac fill. I don't like piston fill because I both need and want to change inks often, and this is far, far easier with cartridge/convertor pens. I can clean at least seven cartridge/converter pens in the time it takes to clean one piston fill, and I don't have to worry about ink waste, or waiting until that big reservoir is nearly empty. Maybe it's the European influence, but we have very different views on things. I never post any pen, with the exception of a couple of pocket pens that have to be posted. Posting a pen is primarily done in America and Japan. Japan has an excuse because of the way they hold a pen to write in their own language. The only reason I can think of for Americans to post so much is because they usually grow up using ballpoint pens in school that need posting. Very, very few pens are made to be properly balanced when posted. This includes the ECO and the 580. You find the 580 a little small and light to use unposted? It looks gigantic in your hand, and while it may be light unposted, the balance is where it should be, which is at the nib. I'm a man with fairly large hands, and the 580 is a good deal longer than it needs to be to use unposted. Many pens are not even made to post, even though I see a lot of videos where Americans are forcing the cap down on the barrel. Brian Goulet speculated that Europeans don't post to prevent theft, but that really has nothing to do with it. The reason most Europeans don't post pens is twofold. One reason is simply that the great majority of pens are designed to be balanced without being posted. Posting moves the balance point, and this causes hand fatigue during long writing session, even when the balance feels fine at first. The other reason is that most still start using fountain pens as children, and are taught early that few things are as annoying as someone who is constantly posting and unposting a pen in a classroom, at a lecture, at a conference table, etc. It's like having someone chewing bubblegum and constantly popping bubbles. This is far worse with snap on caps, of course, but it isn't good with screw on caps, either. Not constantly posting and unposting is also more convenient for the user. You hold the cap in your left hand, using your lower three finger, with the opening up. When there's a pause in the writing, you rest the pen in the cap, holding it in place with your thumb and index finger. The stops the annoyance factor, and is more convenient for the user. Add reason number one and you have two very, very good reasons not to post a pen. Unless you're an American who grew up using cheap ballpoint pens, or a Japanese who uses a pen while holding it far mr vertically than just about anyone else. As for paper, I test pens and inks on the "cheapest" paper I use on a regular basis. I don't need to know how a pen or ink behaves on Tomoe River, I need to know how it behaves on lesser papers. If it works well on these papers, I know it will be great on Tomoe River. If it doesn't work well on these papers, how well it behave son Tomoe River doesn't matter. I still can't use that pen or that ink on a regular basis. This is more than reason enough not to test with Tomoe River. On top of this, I don't like 52 gsm Tomoe River, anyway. Far too much ghosting for me. I do really like 68 gsm Tomoe River, but I wouldn't waste it by testing pens or inks on it because it's just too expensive, and because I already know the result will be completely irrelevant to me. I both need and want to use several other types of paper, and testing on Tomoe River tells me absolutely nothing about how an ink, or even a pen, will behave on other papers. Testing on my lowest grade, commonly used paper, however does tell me whether I can use that ink, and sometimes that pen, much at all. In other words, if it doesn't work on my cheapest papers, I can't use it at all except on Tomoe River. But if pen/ink do well on these lower grade papers, I know both will do extremely well on Tomoe River. Though Tomoe River is far from my favorite high grade paper. I'd rank it fourth or fifth, at best. There are numerous very high grade fountain pen paper out there that most fountain pen users don't even know exists. Even with commonly known papers, I greatly prefer Clairfontaine and Rhodia Premium over Tomoe River.

Aww no broad?
