Did not hold up. Scratched on the first day. Do not recommend.

This was perfect for building a window insert I needed for a spray booth vent. Cuts easily on a table saw. No issues with it on the drill press, scroll saw or spindle sander either. Arrived scratch free. Very pleased!

I dont expect perfection but, your description says unlike other sheets that can be 1/4 short, this is perfect and square, sorry but, it isnt. It measured 23 15/16 across one side (fine), the other side measured from 23 29/32 to 23 5/8 and none of the corners were square. It was however, packaged very well, arrived in perfect condition and is nice and clear!
