Our chip carved fireplace bellows is handcarved out of basswood. We finish the wood with shellac, a natural finish that has been used for centuries. Like all of our bellows, the bag consists of 2-3 ounce leather, very supple and able to produce a strong draft. We build the bellows with a strong steel hinge (covered by the leather) for dependability and a long life. The nozzle is brass. They come with a rawhide lace tied to the handle, making them easy to display. They measure 20-1/4" long, 7-3/8" wide, 5" deep when open, and 2" deep when closed.
