When it comes to mirrors, most people probably think of mirrors that reflect only themselves (such as full-length mirrors, hand mirrors, or three-way mirrors). However, Komi's mirror is designed to observe the movements of other objects and people, and to show "consideration" for others. For example, it can be used to check with a mirror if there is anyone coming around a corner to avoid a collision, or to see if there is someone trying to get into an elevator and wait for them. Komi's "considerate mirror" is useful worldwide, from convenience stores to airplanes.
