Canon GL_101L400 Canon L size. The box has been opened. There are four bundles of 100 sheets each. Three are unopened, and one has been opened. The left side of image 2 is opened, and the right side is unopened. I don't know how many sheets are left in the opened one, but I think there are almost the same number of sheets remaining. I will send it out of the box. #photo #copy paper #glossy paper #printing paper
