Each clamshell is made with soy wax and the lovely scent of lavender freshened slightly with eucalyptus notes. Each clamshell weights around 80gms which will give you a lot of hours of intense scent.
Please note that the shapes and colours might vary from the picture ones pictured in the photograph.
Just place it on your the bowl of your oil burner, place an unscented tea light underneath and enjoy the scent.
When the scent is gone, either soak it up with a paper towel while the wax is still melted, or pop it in the fridge for 15-20min and the wax should solidify once more and shrunk so you should be able just to remove the disk of wax.
