Floortex® Polycarbonate XXL Chair Mat, Rectangular, 60"x60"
Brand New in Box - with slight blemish obtained during shipping
You can't really even see the scuff/stain in the picture because it is pretty small - it is not a gash or a groove and will not affect its durability or the ability of a chair to roll over it
Just one spot has a little scuffing/staining that may be able to be cleaned off - I have not tried.
