What are cosmetic bottles made of?

   - Pros: Lightweight, shatterproof, and often less expensive.
   - Cons: Can be less environmentally friendly unless recycled properly.

3. Acrylic: 

   - Pros: Lightweight, shatter-resistant, and allows for various design options.
   - Cons: Can scratch easily and may not be as durable as glass.

4. Aluminum: 

   - Pros: Lightweight, recyclable, and provides a barrier against air and light.
   - Cons: May require an inner coating to prevent reactions with contents.

5. Natural materials: 

   - Examples: Bamboo, wood, and biodegradable options.

Each material has its own advantages and disadvantages, making the choice depend on factors like product formulation, target market, and environmental considerations.
