yes, like menian/japanese kimono, both of which were permanent tradeable items in game, from the very beginning, but permanent menian/kimono are also sold in store now as well
I heard about tradeable kimonos think I saw one once, maybe...I did not know there are tradeable menians too. I just remember they used to sell perm menians then stopped selling them for so many years ;o;
However the Teal suit had an issue, which prevented it from being released in 2016. Since then, we've released both versions of the suit.
Originally the Red permanent version of the suit was an event exclusive reward for participating players, but has since been sold in special offer sales.
