Parker IM vs TWSBI ECO Black

The Sonnet is intended to be a gift pen covering the low to mid market, but it's so widely counterfeited, including in commercial supply chains, as to be assumed fake until proven otherwise.

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 quality/price ratio is mediocre : whilst certainly not a bad pen, it's not worth the 17 € I paid for. A fairer price would be 12 €.

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

Combining aluminum with plastic also feels flimsy. I just got the Parker IM in gray and black, every once in a while as I hold on to write, I feel a give on the plastic which I find to be cheap. The Everyman aluminum pens are passable, but just slightly under the weight I would like.

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

This being said, before I keep on splurging on my quest to find the right pen, I figured I also need to consider ink types / cartridges.

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! :)
