A leather purse  button is a type of bag or wallet that uses a button as its primary closure mechanism. This button is often a snap button (also known as a press-stud or snap fastener) that clicks into place to secure the contents. The button can be a simple, functional element or a decorative accent.

These purses come in various styles, from small coin pouches to larger handbags. The use of a button closure gives the purse a clean, streamlined look and allows for quick and easy access to belongings, making it a popular choice for both men's and women's wallets and bags.
