If you want to see the video, please search for the same title on Yahoo Auctions. I've created the ultimate soft converter lung for cosplay. Lungs made of hard materials restrict movement and can damage the suit. For example, try putting a cutting board or phone book in your chest and bending forward or backward. You'll find it quite difficult to move. This is the ultimate converter lung made of urethane rubber sponge, cotton, silicone, and felt. It's quite popular. Sew the lung to your suit, etc., around the edge (about 5mm). If you can sew a dishcloth, you'll be fine. Lung size (one side): approximately 41cm (length) / 23cm (width) / 5cm (thickness). Currently, it has a glossy finish, but to make it matte, sprinkle baby powder and wipe it off with a wet towel. Please note that the images are reused, and due to the use of delicate materials like silicone, there may be slight imperfections or errors. Sold as is.
