I think they are pretty rare. They cost 250k rebirth tokens so they are definitely not easy to get. If u have a trade and u wanna know if it’s good then I can help.
Compared to other items they are not that rare. For me the only thing that makes something rare is if they are unobtainable currently and only a few people have it. for example the normal XL Clout. It may have been cheaper but it is currently only trade able.
