The refill of the YOOKER BALL 360° is, in more ways than one, special.
Pressurized with nitrogen at 5 ATM pressure, unlike traditional refills, the YOOKERS 360° refill does not need air to fluidize the ink. This pressurization allows its separator piston to push the ink towards the ball in all circumstances, even extreme ones. Result, under the equator or at the North Pole, at a depth of 40 meters or in space, wherever you are, the YOOKERS 360° ballpoint pen writes without any failures. Its system allows it to propel the ink towards the ball even if you hold your pen with its tip pointing up in the sky!
Hermetically sealed, the YOOKERS Ball 360° cartridge prevents ink from leaking, evaporating or drying out. Even unused for 5 or 10 years, the ink will come out of its cartridge as easily as on the first day.
Its ink with a viscoelastic texture adheres to all types of surfaces, whether smooth, grainy, porous, etc. and attaches perfectly where conventional ballpoint pens struggle to write.
