An art kit is a great idea for any age. My main advice is to try to find one with high quality tools that actually perform well. Don’t buy a cheap marker set.. You can get a lot of marker colors for really cheap, and they will all be bad in a month! Look for high quality sets, even if it means less colors.
This drawing kit is great for anyone who loves to sketch or doodle! This set has a variety of pencil grades, so you can use it to create the desired shading. It also has charcoal pencils, erasers, charcoals, a sketching pad, and a mannequin. You may consider buying some how to draw books with this. When I was twelve, I had some step-by-step books that really taught me some drawing and shading skills. It was a lot of fun!
