Common materials include foam (often polyurethane) for cleaning sponges; nylon and polyester for exfoliating cloths and gloves; and latex-free materials for some beauty blenders.
Sizes vary widely. Small cleaning sponges are often about 2.3–6 inches tall and 3.38–6 inches wide, with depths around 0.7–2 inches. Body sponges and exfoliating towels can be larger—examples include a 4" x 5" sponge and an extra-long exfoliating towel about 3 ft x 1 ft.
Package sizes range from single items to multi-packs. Examples from listings include 1-piece and 2-piece packs, 4-count packs, and single-item (1-PACK) dual-sided sponges.
Rinse thoroughly after use and hang to dry. Some products also list sanitizing options such as placing sponges on the dishwasher’s top rack or briefly heating in the microwave.
