As soon as I opened the box I went to see if I could smell the essential oil right from the cap without opening it and I could! It smelled just like grapefruit sweet and citrusy. I have noticed that when I am able to smell the essential oil without opening that cap that usually means that it will be a strong and long lasting scent when using it with a diffuser. Once I opened up the small sized 10ml0.33 fl oz first bottle of essential oil it had the same smell but more citrusy then fruity. As you can see from the pictures that it has a built in small looking dropper so it isnt going to pour out everywhere when you want to use it . When pouring it will do drops and quiet quickly . This grapefruit essential oil works wonders in an essential oil air diffuser. This is definitely one worth having at home !
