Do you have a child who loves essential oils? Now when they see you putting on your diffuser bracelet, they can have their own! This "Sporty" essential oil diffuser slap bracelet set is red, blue, and green. We also have the "Sweet" set- orange, purple, and pink. <br> If you would like extra felt pads, the 22.5mm size is the insert size. <br> How to Use: Remove the pad from the slap bracelet. Add 1-2 drops of your favorite essential oil- not included- (or 1 drop of a few different oils to make a custom blend) to the reusable felt pad. It does not have to be saturated to enjoy the benefits. Reassemble and take your aromatherapy on the go!
