TWINBIRD Two-Layer Paper Bags Model Number: TC-AF42 Quantity: 4 These are replacement paper bags for Twinbird paper bag vacuum cleaners. They have a two-layer structure that captures fine dust, keeping the exhaust clean. Dust is less likely to scatter when disposing of the trash, making it hygienic. Although they are new and unused, they have been stored at home for a long time, so there are stains on the packaging. There is no problem with use, but please check the photos and purchase with your understanding. *I am also selling other vacuum cleaner paper bags. - Brand: TWINBIRD - Model: TC-AF42 - Type: Two-layer paper bags - Quantity: 4 bags
