‘Trace Elements’ bath salts via Sunshine Soap Company here in York, PA. This place is by far one of my favorite to wander around in downtown.
Disclaimer: I don’t vouch for what the T.S. Pink company claims these bath/epsom salts actually DO for your body, however, 'HowStuffWorks' describe what they are and how they actually work, so check that out.
And these were too cool to not share :)
