This Smithsonian collection pen by Retro51 not only writes with the dreamy rollerball refill, but it also has multiple charming pandas printed on the lightly textured barrel.

Each Tornado is complete with antique silver accents, individually numbered top ring and the Smithsonian sun logo on the finial.

The great thing about Retro is you can convert them from a rollerball to a ballpoint using Parker-style ballpoint refillsor you can userefill with another rollerballshort capless Schmidt refill in this pen.
