Examination of the paper prior to hanging is the buyer's responsibility. Ensure that all rolls are the correct color and pattern, are all part of the same dye lot, have no variation in color, have no print flaws, and that there are enough rolls to complete the job. If any errors in the aforementioned are found, we ask that you contact us right away, and we will promptly reply. Do not cut any of the wallpaper (even rolls deemed fit) in your order prior to speaking with us. By cutting the wallpaper, the buyer/installer has approved the wallpaper for use, and no claims for return may be made. Please note that we will exchange but not refund any wallpaper that is deemed unfit for use. Claims must be made within two weeks of receiving your shipment.
