Moroccan bellows are carved hardwood, which gives the bellows durability and an ornate appearance. They include intricate inlays with typical Moroccan geometric or floral motifs. Bone inlays or carvings are often used to create contrast and add elegance. A flexible piece of treated leather is often used to expand and contract for air compression. Despite their decorative nature, these bellows are fully functional and used for igniting or maintaining fires in traditional Moroccan households.
