This is a set of vintage Burmese lacquerware nesting bowls. The bowls are decorated using a technique known as yun, which involves layering lacquer and then incising a design. The technique was introduced to Burma (now Myanmar) from Japan and is also referred to as "Japan Yun". The bowls are often used as decorative items or for storage, such as holding betel nuts.
