The Girologio 12 pen portfolio leather pen case in oxblood leather is designed to fit pens as large as a Montblanc 149. The 12 pen portfolio case has a snap closure, features wide elastic straps to keep the pens separated, and measures 8.75 inches wide by 6 inches tall. This pen case has a slimmer profile, which makes it perfect to carry in a briefcase or messenger bag.
Exceptionally tall or long pens will fit but may cause the top flap to not close as securely as with shorter pens.
