The cross can be used not only for doctors, but also nurses, dentists, and research scientists. This cross as with all of the crosses can be engraved on the back and depending upon the purpose for giving the cross to someone you care for, it can be engraved for the situation with up to 4 lines and 50 characters. When you select the item for purchase, there will be an option for Engraving. When you pick that option, it will increase the cost of the cross and a box will appear where you can type the message you would like on the back. Just type in your message with forward slashes ("/") at the end of each line and you are on your way to a great memento for that certain someone.
