Thank you for viewing. CLIP STUDIO PAINT Technical Guide to Improve Basic Skills by Kia Inoue, published by MdN Corporation I've only flipped through it a few times, and there are no markings or stains in the main text, but there is a slight warp on the bottom right. The CD disc is also unopened. Non-smoker, no pets, stored by a private individual. Please purchase with the understanding of the above. Thank you.
