Our hanging diffusers are an esthetic way to fragrant your car, closet, boat, RV, or any small space! How does it work? Remove the wood cap, remove the plastic stopper, replace the wooden cap firmly. Once the wood cap is on, hold the bottle upside down for 5-10 seconds until the oils saturate the wood. Tie the diffuser to a secure spot where it will not spill. When the scent starts to vanish, simply hold the bottle upside down to re-saturate the wood. Paraben and Phthalate free Vegan and cruelty free
