These 10 ml. Roll On Fragrances have a masculine scent that both men and women love. Blue Kauai is a bit sweeter with touches of patchouli, mandarin, tonka bean (sweet) and citrus. Coastal Rain is a bestseller which has an amazing combo of lemon, white tea and musk. Sandalwood has an earthy, woody scent. The roll on bottles last a long time and apply smoothly to your wrist or other pulse point. The carrier oil I use for these fragrances is jojoba oil which has a long shelf life and will not go rancid.
