Many of you use essential oils to boost your immune system. So I wanted to make it a bit easier for you. These lava beads on a string necklaces are perfect to diffuse your oils on the go. They are only $6 each. Please mention which string color you would like in the comments. They are about 16.5” long. String available in turquoise, silver, gold (pictured) and I also have black and white string.
