Knob

Three pink and clear glass objects on a gray background. Two pink glass balls are on the left; they are similar in size and shape. The one on the left has a purple tint and the one on the right has white spots. On the right is a clear glass knob with a rounded top similar to the glass balls but with a larger pink top. The clear base resembles an hourglass turned upside down; the bottom half curves inward and then outward.
