Opened but unused. There may be some pet hair on it from inspection. I've tried to remove it as much as possible, but please understand that it may not be completely free of pet hair before purchasing. Fabric: Made of 35% cotton and 65% polyester, a TC material (poly-cotton) that has a natural texture, is durable, and feels good against the skin. It has been treated with mold prevention and water-repellent processing, with a water resistance of 350mm, so you don't have to worry about ordinary rain (an umbrella has a water resistance of about 450mm). Size: Large size, 420cm x 410cm hexagon shape. It has 6 grommets, allowing for various arrangements. Dense Shade: Because it's made of a blend of polyester and cotton, it effectively cuts sunlight and UV rays, creating a dense shade, and excels in light-blocking and heat-shielding properties, allowing you to stay cool and comfortable even in midsummer. Fire Resistance: Compared to polyester, it's a material that is less likely to get holes from sparks from campfires, so you can enjoy campfires under the tarp. In winter, you can relax and spend time around a campfire with everyone. Easy to Carry: It stores at 36x16cm and comes with a dedicated storage bag, making it easy to carry.
