This is an original artwork. The piece is handmade and unique.
Unless there is a strange defect in the materials that cause the piece to change after the purchase, you bought it. It's yours.
Price does not include shipping. Hopefully you can pick it up at the studio in Kensington, CA (next to Berkeley), or arrange for hand delivery of the piece to your location. If shipping is desired, professionals will prepare the crating for safe transport and you will be billed separately,
