This invention relates to bob pins and has for
an object the provision of a hair fastener of this
type which may be inexpensively formed of re
silient material, such as wire, which may readily
be inserted for holding hair in place, and which
is not readily displaced from its hair holding
position.
This invention further contemplates the pro
