The ring portion having at least as many pairs of guide surfaces as retractable writing elements. The writing elements include buttons. Each button is configured to cooperate with a respective one of the pair of guide surfaces of the ring portion. Actuation of the button of a writing element facilitates movement of the writing element from the retracted position to the writing position and returns any of the other writing elements in the writing position to the retracted position, whereby at most, one writing element is in the writing position.

A multifunction writing instrument comprising:
- a body extending in an axial direction and housing a ring portion movable in rotation about the axial direction, at least two retractable writing elements, and a fixed writing element;
- the ring portion having at least two pairs of guide surfaces and the at least two retractable writing elements each including a writing tip and a button, each of the at least two retractable writing elements being movable between a writing position in which the writing tip protrudes from the body and a retracted position in which the writing tip is retracted within the body;
- the button of each of the at least two retractable writing elements being configured to cooperate with the at least two pairs of guide surfaces so that actuation of the button of one of the at least two retractable writing elements facilitates movement of the one of the at least two retractable writing elements from the retracted position to the writing position and returns the other of the at least two retractable writing elements from the writing position to the retracted position, whereby at most, only one of the at least two retractable writing elements is in the writing position;
- wherein the buttons of the at least two retractable writing elements are each disposed radially outside the ring portion while the fixed writing element extends inside the ring portion.
