Four Brothers Marble Runs Editorial Review

The Four Brothers 12 Replacement Chromium Steel Balls are designed for use with the GraviTrax STEM Marble Run game but can also be used with other games that require 1/2" steel balls. These balls are made of AISI 52100 Chromium Steel and are ideal for dry grinding and milling applications where corrosion resistance is not required. They have superior wear resistance due to their through-hardening. Each ball weighs approximately 0.3 ounces and comes in a pack of 20. Customers have found these balls to work well as a replacement for other games such as Bull's-eye Ball and Q BA Maze, although they may be slightly larger than original balls found in those games. **
