Piston-filler fountain pen from Taiwanese pen masters TWSBI
Description

Details

The TWSBI Eco Fountain Pen is perfect for showing off your ink

With no cartridges or converters the TWSBI Eco lets your ink take centre stage

The TWSBI Eco is a piston-filled fountain pen so no cartridges are needed. Ink is drawn straight in to the clear barrel by an in-built mechanism so you can see exactly how much ink you have. And with the ink on view, you can enjoy looking at the ink whilst pondering what to write next.

The cap and end are hexagonal so the pen won't roll when the cap is on or posted. The pen comes in a gift box with a special spanner and silicon grease so that you can  maintain the pen. A leaflet is provided and there are instructions here under the Additional Details tab which explain the basic maintenance tasks.

Key features:

  • No cartridge needed, just use ink
  • Size 138mm closed, 168mm with cap posted
  • Comes in three colour trims
  • Hexagonal shape prevents it rolling off the desk
  • Five nib sizes available

Maintenence information

When refilling your pen

Included in every ECO fountain pen is a quick reminder to wipe the ink off the nib and feeder right after you fill up the pen. This is an important step; only needed when you ink up/refill the pen. If you don't do this, your pen may leak!

Re-greasing your pen

Every so often, approx once a year depending on use, you will need to re-grease your pen using the grease provided. To do this firstly empty the pen of ink and flush with some water. Then unscrew the piston to expose the gap and then use the red tool/wrench provided to remove the pistom mechanism from the pen (turn clockwise). Once out, apply a small amount of the grease to the sides of the plunger by dabbing repeatedly. You only need a small amount so cotton buds are good for this. Re-insert the plunger into the pen and rescrew together. Refill the pen with ink and remember to wipe off any excess ink as above.

When refilling and changing nib/feed

By removing and reinstalling the nib/feeder, air is allowed inside the barrel, causing an imbalanced pressure within. The result is ink being pushed out at a rapid rate. Therefore, after reinstalling the feeder/nib(make sure feeder/nib are seated properly at bottom of the feeder chamber), please remember to use a cloth/tissue to soak up all excess ink on the feeder (Do this also after refills). This will balance out the ink/air pressure inside the feeder and barrel, ensuring smooth operations

Could you please tell me the line thickness for extra fine and fine nibs, please? Do they write as smoothly as the broader nibs? Thank you.

Question submitted by: Xanthe Wells on: 2016-07-31 11:48:14

Bureau replies: Broad nibs tend to lay down more ink and have broader soft spot therefore they write differently than finer nibs. TWSBI ECOs are very nice writers and write a little bit finer than Lamy. Unfortunately nib size in fountain pens is not measured like mechanical pencil, so there isn't an exact number. TWSBI offers a quick guide to nib sizes: 


If you write small, go with an EF
For the normal writer, F is the most popular
If you tend to lean on a bigger font, M will be perfect
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stub nibs are italic in writing style (have a special card or invitation to write?)

What's the nearest nib size equivalent to a Parker IM Premium medium nib?

Question submitted by: Terry on: 2016-07-23 13:53:32

Bureau replies: unfortunately we do not stock Parker, so judging purely by fountainpennetwork and nib nook the nearest match will be Broad and Medium

Question submitted by: Helen Murphy on: 2016-11-02 20:30:54

Does this pen work with non-soluble ink, such as Indian ink?

Question submitted by: Warren Gilchrist on: 2017-01-04 12:06:40

We would only recommend using standard inks in these pens. We are also recommending that only KWZ ink with a batch date of mid-September 16 onwards is suitable. TWSBI pens are quite sensitive and the ink is going straight in to the barrel so best to be cautious.

Answer submitted by: Jo on: 2017-01-04 13:43:11

You say in your blog review not to use KWZ ink and then to use standard ink. What do you mean by standard ink? Can you give me an example? What is it in the KWZ ink that reacts with the silicon? Thanks

Question submitted by: Julia on: 2017-02-19 19:33:13

Bureau replies: KWZ have 2 lines of ink - Standard and Iron Gall. Unfortunately we have no answer to what makes some ink react with some Eco pens...

What is the nearest nib size equivalent to a Medium Lamy AL-Star?

Question submitted by: Matthew on: 2018-05-01 21:14:37

Bureau replies... this is a hard question to answer. We do have a nib chart but it is not easy to measure nib widths and they do vary from pen to pen. I have a Lamy medium nib and were I to buy a TWSBI, I would choose the broad as the nearest equivalent. I think it would be a little wider than a Lamy medium but the TWSBI medium will be finer than the Lamy equivalent so it will come down to choice in the end. You can find the chart here. https://www.bureaudirect.co.uk/blog/fountain-pen-nib-widths-guide/
