I mentioned in a comment that I have a pen case for my fountain pens. This pen case is made by Nock Co. and is called a Lookout. It’s made of 1000D Nylon with DWR coating. I’ve had this one for 3 or 4 years. It keeps my pens safe from damage and not as easy to misplace as a single pen. I checked out their website and they no longer carry this color.
