a. You can request for cancellation if - order is not packed or fulfilled yet & with valid reason. This still depends case to case as there are time-zone difference between you sending us the message and us reading the message hours later.
b. No cancellation if - item is packed and fulfilled, as we are not able to pull it back once the parcel has left us, and without valid reason
*You may choose to ship it back to us but the downside is high shipping cost(higher than the product itself), risk of lost parcel due to different address language, risk of Custom and getting held up with China Custom. Trust me on this.
