Kaweco Paradise Blue ink is a very interesting shade of turquoise. It contains quite a lot of green component. Like a true aquamarine it resembles the color of the waves on the tropical beaches.
Paradise Blue is a well behaved ink suitable for all fountain pens. It has moderate flow, good lubricating properties, and dries pretty quick. This is not a waterproof ink.
As all other Kaweco inks, Paradise Blue comes in 30 ml glass bottle that could be tilted on its side when the ink level will run too low to fill a pen.
