Returns & exchanges
I can not offer returns, refunds or exchanges on chemical materials due to the fact that there is no guarantee that the material has not been tampered with and I can not resell it to someone else with confidence that I have the same materials that was originally purchased from my supplier. Therefore I repeat there are NO returns on chemical materials.
I offer exchanges only on Ceramic art for equal or greater value item. The buyer is required to pay to return the original item shipping and the new item shipping as well as 25% restocking fee. Also for clarity the Free shipping is no longer applicable on exchanged items. The new item will be shipped when the original item is received intact and the additional fees have been paid. No item will be exchanged of a lesser value item with the buyer expecting refund.
