Rated 4 out of 5 by Pete from colorado from Square cut coro The sheets aren't as square as they used to be.

Rated 4 out of 5 by Maureen from Case Pricing I prefer to order coro by the case. First because the substrate comes cleaner and less beat up. Second because of price. Unfortunatly instead of having the price reduction at 24 pieces it is 25. One would think I would get a sealed boxed 24 pieces and one single. Instead I get 25 loose pieces. Ugh. The perfect cut isn't "perfect" but far better then others. Quality drops for unboxed sheets.

Rated 3 out of 5 by bullfrog from Not Bad But Not Perfect Cut These panels aren't too bad and are much closer to being correctly cut than the non perfect cut ones (which are WAY off) but they are still off a bit and are by no means "perfect cut". Oddly they also seem to have a strange bend along the length of the panel meaning they are more like a rectangle with the bottom and top pushed up a bit. See attached image to understand what I mean. I don't know if this is a result of the way they are stored or a manufacturing defect but it can be pretty annoying when sticking a large print or if the customer is putting it in a frame or something.

Rated 2 out of 5 by Frank R from Short and not so sweet review. 2 Stars was generous. Why pay for square sheets that aren't square? To be fair customer service took care of the issue with a single short phone call (like they always do). I think that the ones we got were pulled from the wrong pile. We almost never get completely clean sheets. We actually put on gloves to move these from the truck into the shop. They did offer to start wrapping them on a pallet but we still unwrap it to find dirty hand prints all over the material. Ours might be a one off issue as far as them being square but the handprint thing has been going on for a good while. As for pics, I only had pics of foamcore handy but I can assure you the coro looked just as bad.

Rated 2 out of 5 by John B. from This could have been better Panels were not true square cut. These panels needed to butt up against each other and I had to square them by hand. I do understand the flutes can cause an issue
