Approximately 35.3 x 35.3 x 0.8 Judging from the wrapping paper, I believe two sheets are unused. One of those has a scratch on the back. Please check the second image. One sheet shows signs of use. The remaining two sheets are almost as good as new, but one has a scratch on the back. Please check the seventh image. These are items from a private home and have aged over time. Please consider this and understand that they are being reused.
