Review on High Density Polyethylene Plastic Sheet - Jet Black Shade for Durable Applications by Gary Shakeone

I only bought this to put under a computer which I leave on the carpeted floor for ventilation. If I were to use it for something else I would be very upset at the lack of quality. It has some rounded edges and a few sharp scuffs, scrapes and uneven cuts all around. Almost the roughest presentation imaginable. For the way I use it, that's enough. Buy at your own risk.
