This vase will be a great Halloween decoration. The vase has a spiderweb with a spider and a pretty bow to bring the piece together, and it glows in the black light! You can also purchase some eyeball roses to go with it! It glows best when the black light is hitting it from the bottom because of the way it curves. (This listing is only for the vase!) This vase has a base of 3.25 inches (8 cm) and a height of about 7 inches (18 cm). The bow is about 5 inches long (12 cm) and 2.5 inches in height (6 cm).
