If you don't want to keep writing the code for each item separately, you can also use:

\renewcommand{\labelitemi}{CHARACTER_TO_SHOW}

to globally change the bullets shown by \item command.

Tip

For nested level 1, use \labelitemi.
For nested level 2, use \labelitemii.
For nested level 3, use \labelitemiii.
