Car fresheners/Car Jar These little cuties last approximately 60 days in the winter & 30 in the summer. Phthalate Free These car jars will make your car smell fresh, plus they're absolutely adorable. Prior to use twist off the wood top, take out the plastic plug, twist the wood top back on, and hold the jar upside down for a few seconds to disperse the oils. The wood cap acts as the "wick" like reed diffusers. If you notice your jar not smelling, turn it upside down to saturate the wood cap. When you do this ensure your cap is still secure! The liquid and friction from movement can cause these to come loose, check often! To help reduce the chance of spills, prime the lid and replace the stopper. You will need to remove the stopper each time your lid needs primed. Damage can occur if you do not follow proper instructions. Available in all scent options. WE ARE NOT RESPONSIBLE FOR SPILS!!!
