I found a few cases of this in my basement. Have to be from the mid 90s or earlier based on when the remodelling was done. was meant for a backsplash that never went in. Im selling in a lot of 9 pcs to make it a little over 1sqft. I don't know much else about these other than what's on the box. Please double check this is what you need or want before purchasing as I don't offer refunds.
