Lead markers are a necessity in many hospitals and industrial workplaces. The markers are used on images (X-rays) to determine the side (left or right) of something or some markers can even have a date or patients name on them.
At www.phillips-safety.com we offer many different markers. One example is the Leaded PB Markers for X-rays with Aluminum Backs. These markers are made from durable Aluminum casing that adds density and improves the image and are color coded Red is Right and Blue is Left.-Jessica
