Fabriano 1264 Smooth Bristol Pad, 11 x 14 inch, White
It's very sturdy to use if you're a college student taking art classes. It hold paint, charcoal, and graphite really well. I do suggest if you do use graphite and charcoal to also purchase a sealing spray to spay over it, so it doesn't risk being smudged or get you all dirty when traveling with it.
Good for architecture and interior sketch and industrial design sketch.
