Defect Küchenrückwand - Achatgrau

Despite of waiting for 6 weeks for the delivery, the article I ordered finally delivered with a defect from the production. The Küchenrückwand has a round spot of 1 cm diameter in the middle of the whole 3.5m length roll. It is optically annoying for such a luxury product. Unfortunately I noticed the defect after putting it on the wall.
