Our 10ml glass roller bottles are tinted cobalt blue to protect the essential oils from the sun’s UV rays. Each bottle has a steel roller ball that allows for quick application and a plastic lid to prevent spilling. Our unique labels list the ingredients as well as the directions for application. Ingredients: Copaiba, Marjoram essential oils, fractionated coconut oil. Apply to joints, neck, back, whatever area of the body is in pain and rub in. Use as often as needed. Marjoram oil can have a warming effect. This is a great blend for those who find doTerra’s Deep Blue to be a little too intense. Great for athletes and busy moms alike!
