Hard to find Fujifilm Natura 1600 36 exposures, 20-pack

This is Fujifilm Natura 1600, which has been discontinued. This is a set of 20 rolls, with 36 exposures per roll.
10 rolls expire in July 2019. 10 rolls expire in October 2019. One roll expiring in October 2019 has some box damage.

My impression is that this film has a unique atmosphere that can only be achieved with it. I don't have much time to use film these days, so I'm a bit reluctant to part with it, but I'm listing it here.
I'm truly undecided, so if you're interested, please act fast! :)
