The box and trays are not suitable for storage, and the storage bag doesn't come close to fitting everything and would ruin the oil pastels and charcoal if thrown in together, but the supplies are nice for beginners to try different things out. The drawing paper is poor quality, thin and soft, but again, good for beginners to save money while experimenting. I pulled everything out and put it all into small pencil boxes, pill boxes etc in a small bin so it could be kept organized. I would probably look for a better pencil sharpener, but everything else is adequate and the clipboard is very big and the kids love carrying it around by its handle feeling like artists!
