Value assurance will not be presented for any consumables. No returns will be allowed and no repayments will be supplied. Swapping of new consumable purchases is granted and in which case you should desire to trade it for a unequal width/model/batch, you can directly pay the difference if swapped packet is of larger value.
No quality warranty is provided for any consumables. No return and no refund. Exchange is allowed for unused and intact (unopened if sealed) consumable purchases should you need to exchange it for a different size/model/package and you can simply pay the balance at our sales office if exchanged package is of higher value within few days after purchase.
