Bonds are the paid currency of Arena Breakout: they pay for the Battle Pass, cosmetics and other premium items. Bonds are offered here as a code: the code appears in your account and you redeem it yourself. Unlike the gear you take into a raid and can lose, Bonds stay on the account and only go down when you spend them. If the product name and description carry a region note, compare it with your account.
A region mismatch is not grounds for a refund, so check the region before you pay. If a code does not work, contact support within 48 hours of receiving it, with a screenshot of the error. A delivered code cannot be returned or exchanged.
