Ninja Krowns are virtual, free currency, that can be exchanged to Ninja Packs - unfortunately, please be informed that Ninja Packs are currently out of stock and cannot be redeemed.
We are in the process of developing a new system that will allow you to spend your Ninja Krowns in new ways, as we have deemed the Ninja Packs system to be outdated.
Unfortunately, we are unable to provide any estimate as to when the new system related to Ninja Krowns will be introduced.
The system is still in development, along with the rest of our website infrastructure. Once we are able to share this information, we will surely do so on our social media.
