From Black Lagoon Designs:

"Meet my latest cocktail mug, my glowing Buoy Girl.

The ladies stand at approximately 24cm tall and holds approximately 700mls of your favorite cocktail OR mocktail! They are made by hand from white earthenware pottery, lead free food safe glaze and love.

As you can see from the images the Buoy and light component are separate elements to the mug to ensure easy cleaning (the buoy and light are not suitable for cleaning with liquid) simply place the buoy on the light component and fit into the mug upon serving of your drink."
