These mobiles are perfectly balanced for the most graceful movement. Pull and release the bottom string and watch them fly. Each is constructed of medium-density fiberboard, hand-painted with non-toxic acrylic paint, and decorated with dyed tagua nuts. Best enjoyed indoors in any room of the house. If hung outside, keep dry. These whimsical flyers are handcrafted by a woman-owned business in Colombia and packaged in custom-printed mailer boxes by another woman-owned business in Chicago. Wingspan: 18in.
