Regarding classes

[ZechPet]

May I know what the things inside the containers of each class are?
Also, is a class permanent when bought or claimed from a voucher?
Your help in the replies is highly appreciated!

use the command /gkit and right click on the gkits to check the items inside it
and almost all classes bought from store/goldshop ingame are permanent and it will be mentioned in the /goldshop if a class in seasonal
