Always had to write with a fountain pen at school which was honestly a veritable nightmare being left-handed. At the speed we had to write my hand was constantly 'Royal Blue' and my papers were always smudged and untidy. I still cringe thinking back on it. I never managed to pick up a position where I could write fast, legible, painless and without making a giant mess.

Cue 2025 and I went through my old stuff since I had the sudden urge to give the fountain pen another go. I've gotten a little better at it and managed to adult my way through without too much ink on my hands. 

I'm not sure that it can be identified but I thought I'd give it a shot. The pen is completely unmarked. No logo's, text, anything, ...  I'm guessing it's some cheap off-brand supermarket pen? It takes these short unbranded cartridges as well as the Pelikan 4001 apparently. There is nothing on the nib text-wise but there is a number 4 on the underside. No idea if it's specifically a left-handed fountain pen or not. 

I want to know some specifics in case I want to 'upgrade' or buy a new fountain pen. I'm also interested in knowing what size nib you think this is so I know what to aim for in the future. I'd also love to know if this pen would take any converters. 

Any hints or tips you can give me are most welcome. I can always take additional photo's of something specific if you'd like.

Thank you in advance for giving it a shot.
