Hi George --
I was in the middle of posting a comment that I had one of these for  
over 30 years when your posting came thru!  I think these red ones are  
made of vinyl, but I'll check mine out when I get a chance.  It seemed  
fine the last time I looked at it.  These recordings are, of course,  
prime candidates for archival preservation, so they should be  
manufactured on archival material.  The one I have says "Sutherland  
Lumber."  They're vertical recordings, which is appropriate to use  
Edison's method since these are for acoustical playback.

My original posting was going to say that they do not work well if you  
draw them over your teeth.  As the page discusses, you should draw  
your fingernail over the recording ridges to set the tape vibrating,  
and then you amplify the vibrations by attaching the end to a balloon,  
card, box, or hold the end with your teeth.
