When it comes to quality writing hardware BigiDesign is a company that "knows its onions". I purchased their Solid Titanium Pen + Stylus during their last Kickstarter campaign and absolutely love it. This new design retains the titanium body and quality design finish, yet ditches the cap. Interestingly, while the Ti-Click Pro accepts 35+ G2 style refills, much like its predecessor, the Ti-Click RTS on the other hand takes Parker style refills.
I might have to invest in the chrome coated version.
