This is a good font family. It could be classified as a classy late '70's disco or as a totally awesome futuristic fonts. Basically, what you got here is a really thin alphabet, a thicker one and the thickest one.
Extra Thermal is the thickest possible verison I could make for this font. I think it is easiest to read of the three choices. It is the best kerned, and it emits love. Check out the lovers in this picture. They are totally into this font. He's saying, "Hey baby, why don't we kick back to the crib and type something with Kravitz Extra Thermal."
These font are so plain they becomes super rad. I really want to name these fonts "Rhinestone", but I didn't think this would be the best opportunity this time.
The entire Kravitz family was polished up by the professionals at Font Bros and is available in its new glory in breathtaking OpenType.
