Which materials can nail tips be made of?

Nail tips are specifically designed to enhance the length and shape of natural nails, and they need to be made from materials that provide durability and flexibility to withstand regular wear. The correct answer identifies plastic, nylon, or acetate, which are all suitable materials for nail tips due to their strength, lightweight nature, and ability to adhere well to natural nails or nail enhancements.

Plastic is commonly used for its versatility and ease of application, while nylon and acetate offer flexibility and can mimic the appearance of natural nails. These materials allow for easy filing and shaping, which is essential in achieving the desired nail look.

In contrast, the other options presented consist of materials that do not have the appropriate characteristics needed for durable and effective nail tips. Glass and metal could potentially be too heavy or shatter upon impact, paper and cardboard would lack the necessary strength for use in nail enhancements, and silicone, cotton, or polyester are not suitable as they do not provide the rigidity needed in maintaining the structure of the nail tips.
