The suction cup bud vase/plant rooter is made with copper rod and the best quality suction cup on the market. This bud vase looks great in any window, or on a bathroom mirror. We like to root mint, or basil, and then add a fresh flower from the backyard. It’s a great little gift too. If the window or mirror you attach it to is clean of any dust, it will never fall off. Add a decorative brass butterfly magnet to dress it up.
