A solution applicator comprising a solution container having a frangible twist-off member that enables solution in the solution container to flow out of the solution container when the twist-off member is twisted. The solution applicator also comprises an applicator head having a proximal end and a distal end and a solution pathway extending from the proximal end to the distal end, the applicator head being engaged with said solution container at the proximal end, the applicator head having an aperture and applicating material at the distal end, and the applicator end having a receiving member that the twist-off member engages when the applicator is rotated relative to the solution container to thereby open the solution container at the twist-off member to enable fluid to flow from the solution container to the applicating material. The solution applicator of the present invention is novel in that it includes a twist-off member that retains solution in the solution container until the solution container and the applicator head are rotated relative to each other to thereby cause the twist-off member to be twisted to allow solution to be applied.
