Duo

Another use

I received the Duo as a bonus when I ordered the Field Sling Plus. I personally don't have the need to be that precious with my pens (I usually just carry one), but it doubles up great as a sunglasses case for my aviators that fits perfectly in the zippered pouch on the Field Sling.

Great pencil/pen carrier

The Duo pencil/pen carrier is great. I haven't had to go looking for my writing utensils. I can easily throw it in my bag and it's protected my fountain pens and is easily retrievable.

solid duo

paired with the sling plus, makes toting daily necessities organized and good to go. thank you as well for including the Duo post facto.
