Sailor 1911 Fude De Mannen Blue GT Fountain Pen [****]
Verity nice pen. Feels nice to hold. Good finish and quality. In fact I found it bethe than platinum plaisir. I hope click confessed out worthy similar such models
The pens i received from onlinemantra were scratch free & strong built
I received my delivery just the next day after ordering, and it was amazing to see that the pen was shipped out the same day, just a few hours after I placed the order! I received the pen in absolute perfect condition. The packaging was very secure, and I filled the Sailor Tuzu with Noodler's Baystate Blue Ink. Since I actually had purchased this pen particularly for that ink, the flow, the consistency, and the way the pen writes is just incredible. I also love the adjustable way in which you hold the pen, which makes it very easy to write with. You can write pages after pages and not get fatigued by it. It's an amazing utilitarian pen that everyone needs to have, and it is not too expensive, but the internals, the quality, is no less than a luxury pen.
A cartridge converter pen at a decent price.The nib from Bock is very smooth and wet. Gives a pleasant writing experience.
