Treat every purchase as final: Nice One will not take back or exchange beauty and personal care items, sealed or not, unless they reach you damaged. Devices follow a different rule and can be returned if unused, unopened and in the same state as when they arrived.
For a damaged item, a wrong item or something missing, open a support ticket for the order, or phone the unified number 920033385. With missing items, you will be asked to photograph everything that came, after which they either ship the replacement or credit your wallet.
If you paid in advance using Apple Pay, mada or Visa, your money is returned in between 3 and 10 business days when the order is cancelled before shipping, an item is damaged or the order arrives incomplete.
