3x Absorption! Super Absorbent Microfiber & Waterproofing】 The back of this waterproof folding umbrella case uses super absorbent microfiber, which instantly absorbs water upon contact. Its absorbency is about 3 times that of a cotton towel, providing amazing absorption like a sponge. When you put a wet folding umbrella into this waterproof folding umbrella case, the water attached to the umbrella is thoroughly absorbed, preventing water from dripping. In addition, high-density waterproof material is used on the outside to prevent water from seeping out. ◎ Even if the waterproof folding umbrella case becomes heavy with a lot of water, you can easily wring it out by hand. It's the perfect item for the rainy season. 8-416
