How can glass walls improve spectator viewing at four-wall handball matches?

In traditional four-wall handball, the court is an enclosed space, which historically limited the ability of audiences to observe the game. The development and integration of glass walls into these court structures have significantly improved the spectator experience by allowing more people to watch matches. These transparent surfaces provide clear visibility into the court, enabling fans to enjoy the skillful play that occurs off the back wall, which was previously difficult to observe in fully enclosed, opaque environments.12
