School Smart Railroad Board, 22 x 28 Inches, 4-Ply, White, Pack of 100

Few things. The first is my initial impression. They packaged it better than most other people I have ordered large poster boards or sheets of cardstock from, in the biggest damn poly mailer I have ever seen in my life plus in a nice big sturdy box, but it wasn't enough. A few of the pieces do have some minor bends and wrinkles. Not faulting the company, however this is also the thinnest flimsiest poster board I have ever seen, I never knew it could be this thin. But even with as thin as it is, I still learned that 100 sheets of poster board is almost too heavy for me to lift on my new weight restrictions and am kind of glad that it wasn't the standard thickness or I would not have been able to move it.Now. I had ordered this with the intent to cut down the first several sheets to use as backing for my photography prints, but they're too flimsy, the whole point was to make them sturdier. However, I am not too annoyed at that because while I was waiting for this to arrive, I measure the scrap pieces I have of normal thickness or thicker and it turns out that they are all big enough for me to trim down for print backing and I have enough for either all of them or almost all of them.So instead of getting made and requesting a refund right away, I kept in mind the second reason I ordered this. I knew the prints wouldn't take even a quarter of the bulk quantity and had also ordered this with the intent of drawing on it because my preferred medium is markers, especially alcohol ink markers, and I have found that the best thing for me to draw on that can handle me piling layers upon layers of ink on it is posterboard. So I took the worst damaged sheet and whipped out my box cutter and quickly cut it down to some smaller sizes, slid through like butter, and since I was already working on practicing certain elements for scenery and such anyway, I brought them out to where I was working and cracked down.I really layered on the ink, since that's what I would be doing in a normal drawing anyway and I need to make sure it can hold up at max capacity. You can see I'm the pictures I posted that the poster board is holding up very nicely to all the excessive ink. The heavier darker areas have 12 layers of ink and other than some minor curvature to the paper as a result of over saturation, which quickly flattened itself back out as it dried, the poster board took very well to all of my excessive layering and shows absolutely no signs of peeling.(EDIT: Forgot to add pictures, tried to fix it right away, do not have the option. I guess just take my word.)So over all, even though at first I was initally dissapointed, I am over all still satisfied with my purchase, especially as the biggest drawing I would do would be about half the standard size, meaning all of these will be cut down as I get to them depending on the size I need in the moment and I will be able to get several hundred drawings out of this, and I will probably make this purchase again in the future when I am running out of paper to draw on.
