Sun Barrier 100 Long Umbrella M Size Navy This is a fully blackout parasol that cuts 100% of ultraviolet rays, infrared rays, and visible light. I purchased it from the official website and used it 2-3 times. I usually use other parasols, so I am selling this one because I don't use it much. ■Product Name: M Size / Frill ■Fabric: [Surface] 100% Polyester [Back] Polyurethane Black Film Lamination ■Number of Ribs: 8 ■Length of Ribs: 55cm ■Handle Material: Natural Bamboo ■Total Weight: Approximately 345g ■Umbrella Length: Approximately 80cm ■Material of Center Pole: Black Aluminum ■Country of Manufacture: China (Own Factory) ■Fabric: Japan
