▶ High-tech ink cartridges that can write upside down, underwater with an enhanced ink flow speed when needed.

▶ Best suited for: The Stealth Pen Pro, SWAT Pen, Rebel Pen, and Defender Pen

▶ How it works: the air tight cartridge has a positive pressure pushing the ink out when the ballpoint is activated. This is in contrast with traditional refills where gravity is pushing the ink out.

▶ Each component of these ink cartridges is manufactured with precision. Made in Germany. Packaged in the USA.

▶ In case you are looking for cheaper but still great ink refills to fit the Atomic Bear pens using Parker-type G2 refills, you might love this pack of 6 refills we offer.

NOTE :

We can ship this product internationally, but if you order from outside the United States, it can only be paired (at the moment) with the Stealth Pen Pro.
