CopeYou can comfortably fit 4x3 normal sized pens in the Saki, and even 5x3 with some discomfort. It also downscales nicely, and with fewer pens the empty space doesn't add a lot of bulk. However, there might be better cases if all you want is room for four pens.
longweightI have number of Aston Leather pen cases including a pen case for 4 pens which are US made and great quality! I think their web site is astonleather.com
