Several options. There is normally a spot with the product ordering information to include it. You can include it on the checkout page, or you can email it. mailto:firstname.lastname@example.org If you email it, please provide a reference to something on your order to make it easier to match your instructions with the order. Oft-times the name on the order account doesn't match your email address. We spend a lot of time on this!
"I have about two of these for work. White background, my name and certification on the top and my title in smaller print at the bottom. Arrives quickly and as described in the image it creates for you in the options when you specify what you want typed out. The metal backing is a little cold but I really should wear a camisole under my scrubs when I put it on. Great product, will repurchase as I have been."
