I have used this on rainy days. The folded areas appear dark, and there are some color marks where the inner metal parts touch. Regarding the folds, the blackness seems to fade when stretched, so it seems to be affected by wrinkles. Please check the photos. There are no problems with the opening of the umbrella or the frame.

Please consider this as a guide. This series is popular with a wide range of ages, featuring a Scandinavian-inspired design on 392's original textile, a cotton blend. Depending on the color, the handle design includes bamboo handles and rattan-wrapped handles, and the handles and small parts are carefully crafted, making it a long umbrella that combines practicality and beauty. It is a rain or shine umbrella with 85% UV protection and a water-repellent finish, so it can handle sudden rain.
