For personalization, send information by message Set of 300 Gemstone cards. The physical card size is 3.5"x2". It is a standard U.S. business card size. These cards are a fantastic option for people trying to sell crystals and need some basic information and description about each of their crystals. It took me years to gather and input this knowledge on each card. That way, I can ensure that these cards are brought to perfection as much as possible. As a result, these cards will save you an eternity of time and allow you to focus on your goals and dreams. *NOTE* All of the pictures used on the cards are actual photos taken mainly by us in our warehouse. That means the images are not animated and realistically represent the structure and characteristics of each stone. -Return Policy- Please note that there are NO returns, refunds, or exchanges.
