Buyers should prioritize the rib material and fabric type. For high-end or durable fans, natural bamboo (specifically Grade A polished bamboo) or sandalwood is preferred over plastic due to flexibility and aesthetic appeal. For the leaf, silk, high-density paper, or polyester fabric are common. Ensure the fabric is heat-pressed or double-stitched to the ribs to prevent peeling during frequent use. If sourcing for events, verify that the rivet or pivot point is made of stainless steel or reinforced plastic to ensure smooth opening and closing.
