A4 size thin tracing paper, 50 sheets, high quality 40g/m². - Brand: KOKUYO PRO - Model: Tracing Paper - Size: A4 - Quantity: 50 sheets - Thickness: 40g/m² It is likely unopened. I have not checked for any discoloration of the tracing paper itself. There is a scratch in the fourth photo, but it appears to be only on the bag. It was stored upright on a shelf in a dark place, but the bag in the fifth photo is torn. Recycled packaging materials may be used for shipping. No pets or smokers.
