Rosita RFO 10ml


Our small bottle contains 10 ml - or 230 drops of its precious oil.

10ml RFOThis very rare and unique handcrafted oil - produced from ancient principles given to us from nature and its seasons - has shown remarkable properties through lab-testing and usage. Its naturally high content of antioxidants also gives it a very long shelf life.

Ratfish - chimaera monstrosa - is not related to any other fish species on this planet. The liver is more than 60% of its total mass weight and it has separate anal and urogenital openings. It is one of the oldest fish species known - containing substances and DNA found in mammals, sharks and fish.

The ratfish (also called rabbit fish) is not the same as skate fish or ghost shark, it is not even close to be related to any of these fish species or any other fish species on this planet. And no matter what other sources on the Internet may say, Rosita Ratfish Liver Oil™ could only be found here in this Net-Shop or with other business partners approved by the Rosita Family. (If needed, please ask for these approved business partners and where to find them).

Lab-tests have revealed this oil to contain as much as 33% of the very precious alkylglycerols. "Google search alkylglycerols"

With its estimated 230 drops - depending on your demands, this bottle will be enough for limited usage. It lubricates, protects and de-calcifies with deep penetrating properties on/in very demanding surfaces and systems.
