Paraffin wax bath from Homedics, PAR-150, as depicted in (http://www.amazon.com/Homedics-PAR-150-Adjustable-Temperature-Paraffin/dp/B0...). I have no liners but I am including some paraffin for free. I though mom would like it, but she did not care for it. Used once. Originally around $70.00, asking for $25.00. Mayte
