There are several popular types of wholesale cosmetic bags that are commonly used for storing and organizing cosmetics and toiletries. Here are a few examples:

1. Travel cosmetic bags: These are compact and lightweight bags that are designed for use during travel. They are usually made from durable materials and come in a range of sizes to accommodate different travel needs.

2. Clear cosmetic bags: These are transparent bags that allow users to easily see the contents inside. They are often used for air travel, as they meet TSA regulations for carrying liquids in carry-on luggage.

3. Hanging cosmetic bags: These are bags that have a hook or loop for hanging on a door or towel rack. They are designed to keep cosmetics and toiletries organized and easily accessible, especially in small spaces like bathrooms.

4. Makeup cases: These are larger, more structured bags that are designed to hold a range of makeup products and tools. They often have compartments and pockets for organization and come in a range of materials and styles.

5. Toiletry bags: These are larger bags that are designed to hold a range of toiletry items, including cosmetics, skincare products, and personal hygiene items. They often have multiple compartments and pockets for organization and come in a range of sizes and materials.
