Retro 1951's Tornado Deluxe Albert rollerball pen and pencil set is the perfect gift for that smarty pants that has everything. Heavy duty stainless steel body with glossy black lacquer finish reminiscent of a chalkboard. Albert's famous E=mc2 can be read, along with numerous other formulas all around the barrel. The rollerball cartridge can be changed out for an Easy 9000 ballpoint refill, and refill 1.15mm leads are also available for the pencil. This set's a no-brainer.
