The Square Peg Charlie Horse Kidney has a delightfully unique shape for long-term wear. The original idea for these plugs came from a fan and supporter, Charlie, who wanted something that could be worn comfortably for extended periods and that would react to the motions created by walking or clenching. This unique innovation is what came out of his feedback. The external part of this plug is narrow and long to hug the curve of the body between the legs so that when walking the motion generated causes the plug inside to move slightly.
