Meet the STRYKER: an awesome rollerball click pen precision machined from solid aluminum or titanium. It is assembled by hand and anti-microbial. That means you can let others borrow your pen with peace of mind — as long as you are sure they will give it back. The pen uses liquid ink and is quite smooth. 10 colors are available for you to take advantage of (Schmidt Rollerball Refills). Changing your ink cartridge is pretty easy too. This awesome pen is on Kickstarter right now.
