Final answer:
Pre-formed nail extensions made from ABS or tenure acetate plastic are artificial extensions applied to natural nails for aesthetic purposes or protection. They are made from either ABS, a tough, impact-resistant plastic, or cellulose acetate, a strong, tough plastic.
Step-by-step explanation:
Pre-formed nail extensions made from ABS or tenure acetate plastic are artificial enhancements used to extend the natural nail. They are primarily made from Acrylonitrile Butadiene Styrene (ABS), a common thermoplastic polymer known for its toughness and impact resistance, or tenure acetate, which is likely a typo for cellulose acetate, another type of plastic that has a good balance of properties including high strength, wear resistance, and toughness. Nail extensions are applied usually for aesthetic purposes but can also be used to protect the natural nail
