When people enter public space with their umbrellas in rainy days,
water drop from the umbrella will deteriorate the interior environment.
This product can solve this problem properly.
With a simple push on the handle upward, a handle will emerge on
the top of the umbrella. Turn over the umbrella and allow the raindrops be
storage inside the umbrella. This is a simple and practical approach which
doesn’t require plastic bags.
