This attractive padded pack -- which is like a small folded wallet -- comes with 10 basic Essential Oils: 
 
Wild Lavender, Blood Orange, Organic Italian Lemon, Organic Rose Geranium, Wild Frankincense, Organic Australian Tea Tree, Organic Green Velvet Eucalyptus, Sweet Birch, WIld Himalayan Cedar, and Peppermint in small easy to use 5/8 dram glass bottles (approximately 1-2 mls depending on the viscosity of the oil). Substitutions are available at an added cost depending upon the choice of oil.
 
These oils are highly concentrated and should be used in small doses, averaging no more than 3-5 drops a day on your body. But smelling them as one travels and needs a lift, is a great added bonus. For instance, when traveling on planes, I always drop some strong aromatics on a scarf or tissue and inhale while the person across the way is coughing and sneezing. A little added protection never hurts!
