Is period underwear worth the cost?

Period underwear, also known as menstrual underwear, is a type of underwear worn during menstruation to absorb menstrual flow. They are typically made from a combination of cotton and absorbent materials such as microfiber or bamboo. They can be worn alone or as a supplement to other menstrual products, such as pads or tampons. They are reusable, washable, and designed to be worn multiple times before being washed.
