Ringed Ripple Plug

Pure Stainless Steel. Insertable length 115mm, diameter varies from 4-10mm. 

One picture has complete measurements, one is next to standard #2 pen for size perspective.

 

Plugs are solid, sounds are hollow. NO electrical connection present on this model, but we do have them available or can be easily added with items from our Do-It-Yourself section. A small pad or gator clip is the simplest.
