You know the bargain glasses you can purchase 48 for 20.00  You get them home and realize theyre not a bargain because they break with a slight touch.
This sconce is that glass! 
Its too late for me to return them, but Ill be surprised if they last a year. The glass is almost paper thin.
One came broken, and its being replaced by wayfair. I was shocked at how thin the glass was.
