    Patent number: 8676281
    Abstract: A transparent cell phone protector case where the face of the cell phone is facing away from the rear of the transparent cell phone protector case. This case is a snap fit over the cell phone and sandwiches a decorative accessory color card between the transparent cell phone protector case and the cell phone. The invention is to insert a card of a different color between the back of the cell phone and the acrylic transparent case so that the colored card gives the cell phone protector case a different colored appearance. A set of these colored cards can be sold so that an individual can exchange the color to match the outfit they are wearing.
