I love this! I have several in different designs. They come with 6 different pads to go in them to put your favorite oil on. I can change them to go with my outfit, or change them to put different oils on. I use purple for lavender so I never get my scents mixed. However, if you like to mix scents then you get some great signiture smells. I got this one for a dear older friend of mine who I know is going to love to wear it to church. The cold and flu season is upon us, so it's time to whip out the body armor oil and pour it in. Love this necklace.
