For the past four years I have been in a Van Der Spek pen holder. I switch between my undyed and my Janet Leather ones in this model.
In them I just carry two cheap pens. They have all been pretty hardy and I use them every single day.
The past week though, I have been hankering after something different. Maybe it is because it is summer and I am more free, maybe I just needed a change after four years.
I found this one locally. It is L’artiste by PrintWorks and is in faux saffiano leather, which should be pretty hardy. It cost about €15 in a local department store. You can also find them here
It comes in several designs and colours.
