A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, and first and second concentric writing tips, the second writing tip arranged around the first writing tip, each writing tip received in the housing and able to assume an operating configuration, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose not being deformed when only the first writing tip is in an operating configuration and the deformable nose being deformed when the second writing tip is in an operating configuration, the deformable nose comprising an exit opening of the first and second writing tips, the diameter of the exit opening being greater than the diameter of the first writing tip and less than that of the second writing tip.
A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, the writing instrument comprising a first concentric writing tip and a second concentric writing tip, the second writing tip being arranged around the first writing tip, each writing tip being received in the housing and being able to assume an operating configuration in which the writing tip protrudes from the housing, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose not being deformed when only the first writing tip is in the operating configuration and the deformable nose being deformed when the second writing tip is in the operating configuration and the deformable nose comprising an exit opening of the first and second writing tips, a diameter of the exit opening being greater than a diameter of the first writing tip and less than a diameter of the second writing tip.
A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, the writing instrument comprising a first concentric writing tip and a second concentric writing tip, the second writing tip being arranged around the first writing tip, each writing tip being received in the housing and being able to assume an operating configuration in which the writing tip protrudes from the housing, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose only being deformed when the second writing tip is in the operating configuration, wherein the deformable nose includes an exit opening of the first and second writing tips, a diameter of the exit opening being greater than a diameter of the first writing tip and less than a diameter of the second writing tip.
A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, the writing instrument comprising a first writing tip and a second writing tip, the second writing tip surrounding the first writing tip, the first writing tip being fixed to permanently protrude from the housing, and the second writing tip being moveable between an operating configuration in which the second writing tip protrudes from the housing, and a retracted configuration in which the second writing tip is within the housing, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose only being deformed when the second writing tip is in an operating configuration, wherein the deformable nose includes an exit opening of the second writing tip, a diameter of the exit opening being greater than a diameter of the first writing tip and less than a diameter of the second writing tip.
