I cook very often and when I chose this cutting board I had no idea.  First off it is very large in size I didn’t really pay attention to the sizing when I selected it.  It is also nice and heavy.  I used it as soon as I got it.  I also got the cleaning supplies to keep it looking brand new.  I just love it. i added to my table like decor and I can just use it as soon as I’m ready.
