This is a repeat buy for me. It's a high quality product for an affordable price. Oftentimes, I will see oils sold at stores for more than this for smaller vials. This size will last me a while and is under $5.00.
I take a pipette (A plastic, bulb-headed straw) and dip it into the bottle. I squeeze the bulb at the top to draw oil into it. Then I drop about 12 drops into a full bathtub, by slowly releasing pressure on the bulb. This amount makes my bath water smell so good. This isn't a flowery lavender smell; it is more earthy and strong. I like this style of scent. I find it more potent and calming than the more feminine, delicate versions of lavender.
The net wt. of the bottle I bought is 1 fl. oz. The oil was steam distilled in the USA. It comes in a sturdy, dark amber glass bottle. With essential oils, the darker the glass, the better, as it keeps out sunlight and heat. Those two factors cause essential oils to degrade over time.
