Charm measures 25mmx18mm (approx .9"x .7")
When choosing your design, choose one with clean sharp edges. One with dark lines (thick are better) with a white background works the best. Please remember that the more clear the picture, the more clear the image will appear on your piece. I may have to arrange pieces in your design to fit the charm but your handwriting or image will not change. After completing your order, email your design to firstname.lastname@example.org and be sure to include your order number.
