NOTE: Due to recent technological advances, the ceramic cases used may be steatite ceramic / corderite ceramic / high alumina ceramic depending on the nature of the application. Hence the ceramic cases may be off-white / variations of brown and variations of gray; colours which are inherent to these ceramic materials.
