Platinum Fountain Pen Dye-based Ink Cartridge - Blue Black - Pack of 10

Very good flow of the ink.

Writes very well.

Awesome product by Platinum. Satisfied with the product. Another reviewer rated it 1 star so dear Rohitashwa there is something called import fees which is also levied on each product when it is imported from any other country which has to be borne by the customer. Seems you don’t know this basic thing.

Ink is not upto the mark.

Ersatz Patronen für meine Preppys. Tinte ist gut und passend.

I had a small pile of these Platinum Blue-Black cartridges that came with some other Platinum pens I had bought. They sat in a drawer until I got a deal on a customer-return Platinum Curidas pen without the converter for bottled inks. Lacking anything else onhand I put one of the carts in the Curidas. I really like the ink - combined with the Curidas' EF nib, Platinum BB works well on even the crummiest paper, and the color is even pretty nice for a "manufacturer default" ink. Water resistance is a definite plus. I did end up buying a converter for the Curidas, but I also purchased a pack of these cartridges for use with this pen. It's a very nice utilitarian ink that suits the utilitarian style of the Curidas well.

These are the real, authentic Preppy Platinum ink cartridges. Wonderful for writing, and excellent blue-black colour for writing. Thank you!

Love these ink cartridges, they are easy to insert into my lovely Platinum fountain pen.
