So today i was combing through main site and i saw an update and i was curious on what's it about mainly do we get these rewards after CBT or during that's all?

From main site:
As an extra special thank you to everyone who joins in the Closed Beta Test and lends their efforts to making Onigiri the best it can be, we're giving out all the following items!

EXP Ticket 5000: x2 (10,000 EXP)
Moneybags (30k Ryo): 1
Soul Egg: x10
Hair Accessory: Butterfly Hairpiece

Rewards will be for the actual game launch.

Well since they are wiping accounts after CB I would imagine it would be after launch as well.
