I was wondering about these pens as well, they seem to be a little less refined in workmanship, compared to others, and as a fair proportion of named Indian brands do not even sign their pens, I was wondering if they are as such, but it might be fruitless if we ask the vendor.
Also, there could very well be smaller provincial makers who just make pens without even using a trade name, so these pens might be those.
I'm leaning toward "smaller provincial makers" myself. These aren't as polished, but are pleasant to handle without slipping in the hand. I could put them on my lathe and apply a slurry of Bon Ami, but I really don't care that much for a mirror finish anyhow.
