In the video, a person is seen using a brush to apply glitter to their nails. The brush is dipped into a container of glitter and then applied to the nails. The person's nails are already painted with a base coat and the glitter is being added on top of it. The brush is carefully applied to ensure that the glitter is evenly distributed across the nails. The glitter appears to be silver in color and is being applied in a circular motion to create a sparkling effect. The person's nails are long and appear to be well-manicured. The background is a plain white surface, which contrasts with the silver glitter and makes it stand out.
