This is a special case of the -category of cobordisms.
A complete generators and relations presentation of the 2-dimensional extended unoriented oriented bordism bicategory as a symmetric monoidal bicategory is given in

The 2-category theory in Schommer-Pries’ thesis relies on a thesis by a student of Ross Street:
