In traditional Japanese aesthetics, Wabi-Sabi is a world view centered on the acceptance of transience and imperfection. 
The aesthetic is sometimes described as one of appreciating beauty that is "imperfect, impermanent, and incomplete" in nature. 
It is prevalent throughout all forms of Japanese art.
This Wabi Sabi dish has a small "imperfection" where 2 pieces are upside down.  It is otherwise perfect.
This lovely and colorful tray measures 11" long by 5 1/2" wide
