TWSBI ECO Black vs Lamy LX

Personally, I like the TWSBI eco for its large ink capacity and comfort. It has a good weight to it and there are beautiful colors! :)

My only quibble is the build quality of the grip where it screws into the body and the ink cartridge is attached. It's plastic and feels a little wonky when I screw it in or out - I fear it may not last long. It's a little cheap-feeling.

It uses cartridges, but doesn’t come with a converter. The TWSBI Eco is a great pen that may be more than you are thinking of spending ($30) but is a really nice pen that could be a buy it once and done. It is only bottle fill, and that adds about $10 for ink, but the pen is great and hold a lot of ink. Depending on your use this can be a factor

You'll pay about $50 for one at pen chalet, with one of their easy-to-find 10% coupons. (Try the codes 2Guys or SBREbrown to start.)

Now writing with this pen is where I have my problems. I compared it to the Lamy Safari and Metropolitan Pilot which are both cheaper than the TWSBI ECO and both write several orders of magnitude smoother than the TWSBI ECO. This pen is incredibly scratchy and this was directly comparing to the other 2 pens with 2 different inks. Carbon Ink Black and Waterman Serenity Blue

The pen I received was plastic and not aluminum. Very disappointed with this purchase. UPDATED 16 June 2021 Order this pen from a different vendor and got the same pen. The reason I am giving this a 3-star review is that the pen is not full aluminum nor is the carry case, the outer body is maybe 40% and the rest is plastic

UPDATE March 2019: After over a year of using this pen, I'm my review from 4 to 5 stars. Ink flow is very smooth, and even the slight feedback this extra-fine nib had while writing/sketching is pretty much smoothed out as well. This plastic body is built like a tank; threw it around in all my bags along with keys and phones and everything and there's not a single scratch on it. The massive ink reservoir is also really, really handy for travel and on the go, as I hardly ever have to refill, and the clear body makes it incredibly easy to see when the ink is getting low

We looked at an LX, the last model that is, and other than potential quality there is absolutely zero reason to choose one over a Range Rover.

I really really enjoy writing with this pen. I got a Pilot Metropolitan last year so when I initially picked this one up, I was a little put off by how light it felt in comparison. but after a few weeks of using it I'm super happy with the weight difference - this one really glides across the page (in a Clairefontaine notebook) and it's really nice to be able to switch between a lighter pen and a weightier one. it is also of course very cool & useful to see how much ink is left in the pen

The weight of the pen (without the cap) feels perfect, a bit heavy on the back with the cap. The pen writes pretty well - but my nib (F) is really scratchy for some reason. I've used other LAMY Lx pens, and they felt extremely smooth to write with, so I'm wondering if I got a dud. I can't return it because of shipping fees (I live outside US)
