What kind of toiletries should I pack when traveling?

There are always small bags for traveling in supermarkets. They are empty bottles of different sizes. They are generally not very expensive, about 7 or 8 yuan. You can buy them back at home. Just squeeze in shampoo, conditioner, facial cleanser, etc. and it's ok. . You can use it after you come back from traveling. It's light and easy to carry. It's also waterproof, so you don't have to worry about the towel getting wet.
