Product Description It's a little curious, these life-sized organ made entirely of felt. But hey, Felted Curiosities is what we do!This listing is for one HUMAN-SCALE set of lungs. SIZE: Approximately 12" x 14" The lungs are a fleshy pink wool with a texture suggestive of capillaries. The lungs connect to a trachea in the center. Other felted organs are available: spleen, gallbladder, appendix, brain, lungs, uterus, tonsils, stomach, intenstines, etc. I've been honored to have my handmade organs featured in an award winning ad campaign (Gyro Denver - 2013).
