Masks' needs to be replaced every so often. However, there are times when this is not possible... So in times like these, We need "MASK FRESHENER" a cool and fresh scent that allows one to extends a masks' use time until a fresh one is available. OR with initially three available aromas... ROSE... Ylang-Ylang... and Lemon Grass, one can just enjoy their minty aroma to sweeten and make your day at work...
