• an exterior wall, wherein the exterior wall covers an outer surface of the drinking vessel, and wherein the exterior wall length longer in height than the inner wall, and wherein the exterior wall rests like a flap on the outer surface of the drinking vessel;
• a plurality of ribs, wherein the plurality of ribs is located on an inner side of the exterior wall, and wherein the plurality of ribs is configured to maintain a structural integrity of the exterior wall, and wherein the plurality of ribs covers an extra space between the attachment and the drinking vessel, and wherein the plurality of ribs is equally spaced curved and slender column in structure, and wherein the plurality of ribs provide thickness to the attachment to prevent the attachment from falling flimsy;
• a curved surface, wherein the curved surface joins the inner wall and the exterior wall, and wherein the curved surface rests on a rim of an aperture edge of the drinking vessel;
• and
• a curved edge on the curved surface, wherein the curved edge is a half semi-circle cut on an edge of the curved surface, and wherein the half semi-circle cut is configured to cover up a gap between an inner ceiling of the curved surface and the rim of the aperture edge of the drinking vessel, and wherein the half semi-circle cut avoids protrusions on the aperture edge of the drinking vessel.
