Very thick, yet flexible enough.. and so far had kept it’s clear sheen without clouding.I used it to build my own doggy door and this was sturdy enough to keep the wind from gusting through and it didn’t want to rip/tear when held in place by a trim board and screws.I also used it in the same application method to cover digital push bottom code entry locks on my backyard gate because they aren’t weatherproof.I just cut a flap that drapes over the lock body and it works perfectly to keep the rain off of the electronics.What comes is EXACTLY what is described.Oh.. the plastic is not perfectly clear. It appears to have a blue-ish sheen, yet still allowing great visibility through the product.
