Enchanted Tree Plug In Melt Warmer.
The second photo isn't the plug in warmer, it is the stand alone warmer. Using the image for illustration purposes only, but obviously the plug in is a smaller version of the free standing unit and the design is exactly the same picture.
Soy wax melts can be purchased separately on the website.
Also available; Enchanted Tree Melt Warmer standard size & Diffuser standard size in Enchanted Tree design.
