Since I'm a huge Poopikat fan, I'm probably not particularly objective :D I love the selection of high-quality materials, and the paper in the mixed media sketchbooks is my absolute favorite. The instructions in the booklet could probably be more detailed for beginners, but since I'm familiar with Poopikat's technique, they're sufficient for me. Unfortunately, I do have one major complaint: the cap on the Sakura Pigma Brush wasn't on; it was lying loose in the material bag. The bag soaked up the paint, and the tip of the brush is now bent. The brush also seems to have lost quite a bit of its color. It's basically unusable as a result. Still, I'm very happy to finally own the art kit :)
