Small magnetic compasses are great for classroom physical science activities such as tracing magnetic fields of bar magnets or nature activities. Each compass has a magnetic red and white needle encased in cylindrical black plastic case with clear plastic top. The black backing with green cardinal directions and white intermediate directions provides clear visibility. Approximate diameter is 1.5 inches..
