A tampon applicator has a barrel and a plunger. The barrel extends from a proximal end to a distal end, the distal end having a base opening, and the proximal end having an upper opening exposing an inner chamber. A window formed in the barrel is shaped to receive a tampon. A set of protrusions extends inwardly from the inner chamber proximate the distal end of the barrel, and an inner ring of the inner chamber is proximate the distal end of the barrel. The plunger extends from a first end to a second end, the first end having a base. A top ring is on the base of the plunger, wherein the inner ring of the barrel is adapted to removably snap into the top ring. A annular ridge is on the second end of the plunger for threaded engagement with the set of protrusions of the barrel.
