In recent years, large typhoons and unstable weather have been seen in many years, due to the bomb low pressure, etc., suddenly intense guerrilla downpours. In addition, this water damage is difficult to predict and difficult to measure. Do you have trouble getting a sandbag (sand) such as "heavy, no soil" when it comes to water damage preventions? The "Dash Bag" is a sandbag that does not require soil at all. You wont know when water damage will occur, but even elderly people and women can inflate the dash bag about 33.1 lbs (15 kg) in the home (also rain water during intense downpours, typhoons) in about 5 minutes per bag, making it very easy and quick to set up as needed. It is very convenient and safe. With the "Dash Bag" you can usually store in a small amount of space such as an interior loading or a door in your room, so we recommend that you prepare it as an emergency water damage prevention tool.
