The video shows a person using a bottle of blue nail polish to paint three dots on a pink phone case. The person carefully places the dots in a triangular formation on the case. The video is shot from a close-up angle, focusing on the person's hand and the phone case. The blue nail polish contrasts with the pink color of the phone case, making the dots stand out. The person's hand is steady, and the dots are evenly spaced and sized. The video ends with the person stepping back to view the finished design.
