Customer Reviews
Less shiny than I thought
N.K. from USA, Pennsylvania
I ordered these balls for an art project. They were fine but the picture led me to belle they were going to be a very shiny silver when in fact they were less so. I can use them but was somewhat disappointed. Company was professional and easy to deal with. Would buy from them again.
