This product is not .2 of an inch thick which translates to approximately 13/64 of an inch. nor is it .6 which translates to approximately 39/64 as described in dimensions. This plastic is nearly as thick as cardstock. It is very floppy and will not hold its shape. I am disappointed. I purchased some plastic poster board a few months ago that was indeed 1/1634; thick and it was perfect for my project. But I cannot find any sturdy thickness anymore. So I am returning this product due to an inaccurate/ incomplete description. It would be perfect for someone that needs something permanent for tracing. If that is what I wanted it for I would give it 5 stars.

It's pretty flimsy. I don't know if I would call it poster board. I'd be unlikely to buy again.
