A dosing cup having a longitudinal axis includes a base; an opening opposing the base, wherein the opening is circumscribed by a rim; and a sidewall extending from the base to the rim. The sidewall includes a first portion extending from the rim toward the base. The first portion has a projection with a dosing indicium. The projection is defined by a length extending axially along the sidewall and a width that is perpendicular to the length. The width of the projection is less than the length of the projection. The sidewall includes a second portion extending from the base toward the rim. The second portion has a recess. The projection of the first portion mates with the recess of the second portion. The first portion has a first translucency and the second portion has a second translucency, wherein the first translucency is different than the second translucency.
