Approximately 3.5 inches diameter, 5 inches tall. I can picture a Slytherin having this on her desk. "These cunning folks use any means to achieve their ends..." Don't submerge in water or use for food/drink. To clean (if necessary) just damp cloth it :) These are perfect for holding your colored pencils, pens, markers, makeup brushes, etc. I've decoupaged these plastic tumblers with leftover pieces from other projects, and sealed with acrylic. Everyone who has been in my studio knows I can't part with even the smallest bit of cute paper or fabric if it can be used for another beautiful thing. I adore decoupage because its so unpredictable, I never know how it will turn out at the end. If you love your décor chaotic, kooky colored, randomly textured, and entirely one-of-a-kind, my pieces are definitely for you <3 Please visit www.lemonlady.etsy.com to purchase
