Spider-Man does anything that a spider can, which includes crawling up your coffee mug! OK, that would totally suck if a spider crawled up your coffee mug, but this great coffee mug sure doesn't suck! This Spider-Man Webbing 20 oz. Black Ceramic Mug features an image of Spidey swinging on a spider web background. Perfect for Spider-Man fans, not so great for arachnophobes. Holds up to 20 ounces of liquid. Hand wash only. Not dishwasher safe. Do not microwave.
