Welcome to Glass-Holes.com.  We have been hand fabricating overflow boxes since 2007. We invite you to browse through our store and shop with confidence. Your satisfaction is guaranteed. If you don't like it, email us and send it back. Due to the many variables involved in the drilling of glass, including your skill level, we cannot guarantee your tank against damage caused by drilling. There are few things in life as enjoyable as aquariums. We do our best to provide products that help improve water quality, and therefore good health in your aquatic friends.  We hope you enjoy your stay.
