This is a well made valet. It is just the right size for the small table that I wanted it for. The leather seems of good quality and the silver metal accent gives it a nice touch that blends well with my decor! This is definitely a nice buy if you are looking for a valet! For my needs, I wanted one with a leather interior vs the velvet or suede so it would be easier to clean - this fit the bill!
