This is grid-patterned kraft paper from SAKAE Technical Paper. One side has a grid pattern (printed with thin lines), and the other side is blank. The size is A3. The details of the listed product are shown in the third image, but the outer packaging, which had a label, has been opened due to damage. The contents, 10 sets of 25 sheets each, are unopened. I collected various papers, but I can't use them all, so I'm putting them up for sale. For those who need them. Shipping will be in a cardboard box. The cardboard box will be reused. Please understand. Thank you.
