Material - The umbrella is coated so it won't be water-permeable or leaky even in a downpour. The handle is made of magnesium-aluminum alloy. Wind and Rain Proof - The folding umbrella is made of 8 rust-resistant reinforced fiberglass ribs, which are lightweight but durable to withstand rain and wind. Anti-UV - In order to effectively block UV rays, a black glue layer is added to form this UV-proof umbrella. Reflective and Rounded Edges - The umbrella is manual and has a safe slider with no sharp edges to hurt your fingers. The corners are rounded, so there is no worry of getting hurt. The non-sharp edges make it feel better in the hand, and there is even this area for light to reflect, making it easier to see at night. Compact Travel Umbrella - A lightweight and compact travel umbrella is a great choice for you to carry with you.
