The Esterbrook Nook Case is handsome and well constructed. It's much more substantial than a pen roll or other soft pen case, so if the safety of your pens is a priority, it would be a good choice.
However, at $76.00, it is expensive. I could see paying that much if it were made of real leather, but for synthetic leather I think it is over-priced. I honestly expected the case to be around $25.00.
You can purchase the Esterbrook Double Pen Nook Case from Goldspot Pens for $76.00. Other sizes are available as well, including single, triple, six-pen, and twelve-pen cases.
(Goldspot Pens provided the Esterbrook Double Pen Nook Case to Pen Addict free of charge for review purposes.)
