1. An ice maker comprising:
a first tray that is made of a flexible material and defines a first chamber; and
a second tray that is made of a flexible material and defines a second chamber, the second chamber being configured to move between (i) a closed position at which the first tray and the second tray are in contact with each other for ice making and (ii) an open position at which the first tray and the second tray are spaced apart from each other for ice separating,
wherein the first chamber and the second chamber are configured to define an ice chamber based on the second tray moving to the closed position,
wherein the first tray and the second tray comprise a chamber wall that defines the ice chamber, the chamber wall having an opening that is defined at an upper portion of the chamber wall and that is fluid communication with the ice chamber, and
wherein the chamber wall comprises a surface-treatment portion that is provided at an inner surface of the upper portion of the chamber wall and that is configured to increase attaching force between the inner surface of the chamber wall and a surface of ice in the ice chamber.
