I have seen a bottle of P Mark Kach Ghani oil in my kitchen for years and it was well trusted brand in indian kitchens for years now.
I use mustard oil in all aspects of my life i.e for my hair, for my body oinment, in food etc. So for me the quality of oil is use should be top notch and witb P mark I know my health is in safe hands. I have always had a great experience using there oil and seriously I would request all the readers to integrate mustard oil in your daily life & with P mark you will never have a complaint.
