The leather is supple and well-made seams. My fountain pens are well protected from external shocks and them with a leather partition. The only gripe I have about this case comes from the flap of the retaining strap which is greenhouse too which needs to be cautious to slide under the flap strap. In fact I close the case properly only in the evening when my fountain pen found my bag.
Bought 8.09 euros to the company Office Stock Direct, which is very reliable.
(Edit: Actually after the initial running, flap and strap slide smoothly now)
