Here is a Wax Free Fragrance Warmer from WESTINGHOUSE.

It is Terra Cotta Red and features a Flickering LED Light and a Vanilla Fragrance Disk.

The Heater is safe to the touch (not hot) and the unit measures about 4 1/4" diameter.

It is Brand New - Never Used.  Additional Fragrance Disks may be purchased from Westinghouse or from another online seller.

I have a similar one in White currently listed on eBay!
