Using your personalized pet phone case is a piece of cake. Just gently slide it onto your phone until it fits snugly. When taking it off, start from one corner and slowly peel it away. As for maintenance, a simple wipe with a soft, damp cloth is all it takes to keep it clean. If it gets dirty, you can even use a mild soap. Remember, the preview images might look a bit different from the actual case in terms of color. Don't worry if you notice a small variation. Also, try to avoid dropping your phone to make the most of the case's shock - absorbing feature.
