These beautiful little hearing aids are custom cast and molded to the ear of J.L Hiller. They look like little snails that are ready to crawl into your ears and hum at you. One is amber in color and the other is a clear acrylic cast. Very surreal little electronic hearing snails that come with original owners manual and certificate for Mr. Hiller made by Hearing Aid Dealer K. P Fryer sold as a set.
