These look wonderful and totally fit my cherry blossom/Japanese kitchen theme! 
It says to hand wash to not scratch them etc. but I've been running them through the dishwasher just fine and they still look brand new! 
They feel great to use - not too heavy (like the last silverware set I replaced) but they're also sturdy and do not feel flimsy like cheap flatware.
Very pleased and if I start entertaining more I'd be happy getting another set!
