It's a Damppit (spelled something like that). (I bet they have a web site - try different spellings). Very common for string instruments and woodwinds. Some are placed in the f holes of violins, etc. Others, just in the case. Lots of different diameters and lengths available. Usually green with black endcaps, but might be in other colors as well. Or maybe there is a "take-off" copycat manufacturere. I remember there being a push for using them in pianos somewhat over ten years ago. I think they used to be just cellose sponges cut into strips and rammed into tubing with holes, then ends capped. Maybe the absorbant material has been changed over time. I don't think they release enough humidity for a piano, not to mention other factors. Certainly not the control a Damppchaser system gives. Fred Sturm University of New Mexico Dorothy A.
