Perfect size, I carry the required writing gear for the field, if I need more room, I have the larger Lochby pen case as well. Good stuff!

The Duo is a wonderful protector keeper of my writing instruments. It holds up to four pens (fountain, rollerball and ballpoint) and pencil with eraser comfortably and safely in my purse or matching sling. I love it.
- BBBrantley B.Verified BuyerRated 5 out of 5 stars2 weeks agoGreat EDC Pen Case
Great product. Materials are sturdy and stylish. Excellent workmanship. I can actually fit about four-ish pens inside. The external wrap-around pocket is a great feature for extra EDC items or safely stashing away a pen in your bag if you're on the go. Can't go wrong with the YKK zippers. As always, Lochby didn't disappoint.

Perfect sized, protective duo pen case for travel and daily work. Well made as is typical for Lochby items. I can recommend this easily.
