Black cosmetic bags in this selection are commonly made from PVC, polyester (including recycled polyester), and polyurethane.
Options range from unstructured single-compartment pouches with no pockets to bags with multiple compartments or interior pockets; some designs include two compartments or several interior pockets plus a front zipper pouch.
Several listings describe water-resistant or waterproof construction—examples include water-resistant nylon shells and waterproof PVC exteriors—providing spill protection for toiletries and cosmetics.
Sizes span small pouches to larger toiletry bags. Example dimensions from listings include 2" H x 7.5" W x 5.25" D; 5.5" H x 10" W x 4" D; and a three-pack listed as small (7.9 x 5.1 x 2.4"), medium (9.1 x 5.5 x 2.4"), and large (10.6 x 6.7 x 2.8").
Care guidance varies: many specify "Spot" or "Wipe Clean," some recommend "Wash with soap and water," and at least one listing notes that care instructions are not provided.
