This could potentially be turned into a save the date magnet, but this design is actually a favor magnet. The idea is to send them with thank you cards as a momento. At 5x3.5 inches, this design fits 3 nicely sized photographs, the wedding date, and the couple's names. Along the horizontal line, we can even fit in the married last name.
In this case, the lines are teal colored, but whether that is a good option for your personal version really depends on the photographs; It might turn out that the lines should be white or black to contrast with the photographs, in which case, that curved border and the names could be in your wedding color.
