With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.

Parker Premium IM Retuals Green Gradient GT Fountain Pen
First scented ink for me and it really put to shame the next ones I got. Has the smell of Kopiko sweet. This has a very pronounced and bold smell unlike other perfumed inks that has a faint mild smell. Really made my room smell like coffee when I accidentally spilled most of the ink of a full bottle. But I ordered another immediately as the ink was that good.
Coming to the color of the ink It has a nice dark brown color with some shading as well. No Sheen observed in TR68 paper. The ink isn't that dry but not very free flowing either. There's some viscosity to the ink. Not sure how it would perform on a dry feeding Pen. But this ink really deserves a wet medium to broad nib to put down that much ink to make the room smell nice as well as see the shading of the ink.
Genuine product , good customer service !
EF is too fine tbh , if you are considering a nib size for daily use , exams or to see the rich colour of your ink go for fine

Sailor 1911 Casual Black CT Fountain Pen
Not surprised this is one of Taccia's best selling inks.
I do not understand which fountain pen is for beginners and which one is for the experts! But writing with this pen is practically a charm. It is smooth as well as having a very pleasant feedback. The service of OnlineMantra is very prompt. I have received the pen within a week in Kolkata.
