Very Old Stock or Very Poor Packing
I get the impression that this is very old stock, it comes folded into 3, stuck together with sticky label, that label is seems to have once been white, but has yellowed where the 'glue' has penetrated the sticker. Also when you take the sticker off to open up the mat, you are left with a VERY sticky mess. After hours of cleaning with products like WD40, you can just about get rid of the sticky mess, but it still leaves a stain.
Otherwise its seems a good product, seems to stay cool pretty well
