The Montblanc Writers Edition Sir Arthur Conan Doyle Limited Edition Rollerball Pen pays tribute to detective Sherlock Holmes. The blue-gray resin body is modeled after the foggy London sky where Holmes solves his cases. The cap and barrel are decorated with a plaid design inspired by Holmes’ coat. The pen clip is shaped like a magnifying glass and features the initials JB in tribute to Joseph Bell, the inspiration for Sherlock Holmes.
