SELF ADHESIVE BACKED BLACK NEOPRENE SPONGE/FOAM RUBBER SHEET 300MM X 300MM X 1.5MM THICK (One Side)

This could of been a 5 star product. In fact, it really should be, as there isn't anything actually wrong with it. But the one I received had a 3-4mm hole in it. Fortunately, for my purpose it didn't matter too much BUT - something to bear in mind. It isn't that cheap to buy either. Gah. So much for waterproof. And it arrived rolled up, Not a problem per se, but it causes a bit of creasing, which does actually come out after a short while.
