This heat pack cover is made from traditionally dyed indigo fabrics from Rajastan, a timeless classic. Filled with wheat and soothing sandalwood, this herbal pack moulds to any body shape, applying dry heat, gentle pressure and plant power to work on your aches and pains. A characteristic of true indigo is that there can be some colour rub off - this colour isn’t harmful - indeed many cultures use indigo in cosmetics & medicines. Indigo pattern cannot be chosen and is dependent upon fabric in stock, sorry.
