• Double layer of soft, luxurious 100% organic cotton flannel pad with a hemmed border and slits on each side.• Can be used as an extra layer inside your Queen of the Thrones® Pack for Abdomen (sold separately) by threading the straps through the slits on each side to help extend the life of your Liver Pack.• The 100% Organic Cotton Flannel can also be used to do “traditional” Castor Oil Packs (simply add Castor Oil and place it to the body) but please note this won’t be less mess.
