[Tex/LaTex] Reduce size of \bullet character in lists

Question

Example for a list using mdwlist:

\begin{itemize*}
\item First
\item Second
\end{itemize*}

The bullet symbol for the first level can be redefined with:

\renewcommand{\labelitemi}{$\bullet$}

It apparently uses a math environments symbol by default.
I would like to reduce the size of it, but font size modifiers like \tiny seem to be invalid.

Answer 1

For centering material vertically you can use \vcenter, but this only works in math mode. Thus you need to enter math mode twice:

\renewcommand{\labelitemi}{$\vcenter{\hbox{\tiny$\bullet$}}$}
