Are you going to use it? Do you have a use for it? This is a flexible duct handled by TRUSCO. It's a disposable type. For things like paint spray mist and dust exhaust from grinding work! Replace it when it's torn! It's a vinyl type. The bellows are fine, so it's flexible. If the inner wall is dirty... Tap it lightly or kick it! It will come out from the exhaust port^_^ If it's torn in a few places after long-term use, repair it with tape! It's long, so you can cut it to any length with a cutter knife! You can buy it on Amazon for around ¥8000. Reference ↓↓ https://amzn.asia/d/8AimlZy Not for exclusive listings. Packing materials are reused. Use of bubble wrap and other vinyl is kept to a minimum. Thank you for your understanding. * Unless there are special circumstances, it will be shipped from Yamato Transport office. Transportation is fast, but we cannot use Eco-Mercari delivery!
