Decorated products, such as toothbrushes, of substantially the same type and having substantially the same features (preferably functional features) except for a decorative element. The decorative element on each product is selected from a plurality of different decorative elements such that the products may be visually or aesthetically differentiated from one another by the differences in the decorative element associated therewith, while otherwise having the same functional characteristics. An exemplary embodiment is sleeved adult toothbrushes, the sleeves each having one of a variety of designs, the set of available designs including designs of different categories to appeal to different consumer bases (e.g., different ages, genders, styles, etc.) or to signal a time period for use of the product (e.g., a variety of designs for each of the four seasons to signal changing the toothbrush each season). Preferably, the products are decorated with a design selected from more than one category of designs, at least two of which categories include more than one design. The designs may be changed for the product line on a regular or semi-regular basis to refresh the appearance of the products.
