School Smart 1485744 Railroad Board, 6-ply Thickness, 22" x 28", Black (Pack of 25)

my issue with this product is that 6ply is not a measurement of thickness. And while would be an indication of how stiff the board would be. The description needs to include the Mils thickness to give a fuller specification on what you are getting. The product was not really thick enough for my use.

This is an outstanding company. I purchased a pack of School Smart Railroad Poster Board Paper and found it was not stiff enough for my purposes so they issued me a full refund.

Not the best quality paper. Good for cheaper projects, not for presented art. But amazing customer servive/support

The paper is heavy and fairly stiff as advertised. The package was incredibly flimsy and arrived so battered I was surprised the paper wasn't damaged more than it was. Fortunately I purchased 22 x 28 inch sheets but only needed 18 x 24 and was able to cut around the damage. If I needed the entire sheet I would have returned it.

This is just posterboard, not railroad board. It’s the same thickness as the flimsy poster board from a dollar plus store.
