What is a signature brick you ask...let me help!!! A signature brick come with two bars. They are divided into small sections to all them to break apart easily. You can then decide if you would like one, two or three sections in your warmer. The really cool part is our logo is place on the top of each brick section. Signature bricks are usually one scent. Pop it in the warmer and the aroma will make your house smell amazing within a few minutes!!! Don't see your scent, let us know and we do a custom pour for you!!!
