Due to differences in photography lighting and each monitor, there may be varying degrees of color difference. Due to manual measurement, the size of the product may differ by 0.5-1cm. Please allow for slight size errors. Thank you for your understanding! If you like our product, please give us a good review. Thank you. Be careful: To make a purchase, you must check the recommended tissue size and drawing number. As long as the size is correct, the drawing paper will be smooth and will not get stuck or damage the paper!! The basic problem with poor paper drawing is related to size.
