Srry for bad pic quality i just took them fast It was produced by carlsen The case was saled around January in Germany and maybe austria for a price 24€ sadly apparently there was no informations that the case is limited. It was saled on amazon, Thalia( German book store) and in 1 maybe 2 more stores. After 1/2 days after relase they went out of stock and it made fans mad cuz there was no info about the limited stock and some fans got a damaged case wich couldt be replaysed anymore.

After it the resale price was for around 40~50€

Some months later carlsen decidet to sell again the case with extras during the 7th band relase on november. This time it costed 30€. And there was all in one ediction where you could get all volumes with case for 138 € Idk if these 2 are limited too.

Some price info: every volume costs18€ expect the 7th it costs 20€ So you can see that the price of case went high.

Aswell in some book stores you could find a papaer stand. Sadly its only book stores exclusive and carlsen dosent sales or gives leftover stands.
