I'm looking for a way to produce a blackboard bold version of numbers - not just 1 or 2, all of them. I've tried bbm:

\documentclass{report}
\usepackage{bbm}

\begin{document}
    $\mathbbm{1}$\\
    $\mathbbm{2}$\\
    $\mathbbm{3}$\\
    $\mathbbm{4}$\\
    $\mathbbm{5}$\\
    $\mathbbm{6}$\\
    $\mathbbm{7}$\\
    $\mathbbm{8}$\\
    $\mathbbm{9}$\\
    $\mathbbm{0}$\\
\end{document}

But this only works for 1 and 2. How can I get the other numbers in a good quality?

Another package could be mathalfa with option bb=boondox.

enter image description here

\documentclass[a4paper,12pt]{article}
\usepackage[bb=boondox]{mathalfa}
\begin{document}
$\mathbb{1},\mathbb{2}, \mathbb{3}, \mathbb{4}, \mathbb{5}, \mathbb{6}, \mathbb{7}, \mathbb{8}, \mathbb{9}, \mathbb{10}$
\end{document}

    $\mathbb{2}$

    $\mathbb{3}$

    $\mathbb{4}$

    $\mathbb{5}$

    $\mathbb{6}$

    $\mathbb{7}$
