[Tex/LaTex] Double column document with tcolorbox that spans both columns

Question

I am trying to make a document so that a colorbox, in a double column book document, spans both of the columns nad I do not know what to do. Here is my test.

\documentclass[10pt,twoside,twocolumn,openany]{book}
\usepackage[most]{tcolorbox}
\usepackage{xcolor}
\usepackage{lipsum}

\definecolor{monstertan}{HTML}{FDF1DC}  %e.g. used for newer monsterblock
\definecolor{iron}{HTML}{CBCDCD}    %e.g. used for older monsterbox
\definecolor{undergold}{HTML}{C9AD6A}   % e.g. used for titlerules
\definecolor{uppergold}{HTML}{B89A67}   %e.g. used for pagenumbers and footer
\definecolor{brass}{HTML}{B5A642}
\definecolor{copper}{HTML}{b87333}
\definecolor{black}{HTML}{000000}

\DeclareTColorBox{paperbox}{O{} m O{iron}}{
    frame hidden,
    boxrule=0pt,
    breakable,
    enhanced,
    before skip=11pt plus 1pt,
    toptitle=3mm,
    boxsep=0.25ex,
    left=8pt,
    right=8pt,
    fonttitle=\fontfamily{fosj}\selectfont\scshape\bfseries\color{brass},
    fontupper=\fontfamily{lmss}\selectfont,
    title=#2,
    arc=0mm,
    parbox = false,
    borderline north={1pt}{-0.5pt}{brown},
    borderline south={1pt}{-0.5pt}{brown},
    colback=#3,
    colframe=#3,
    colbacktitle=#3,
    fuzzy shadow={0mm}{-3.5pt}{-0.5pt}{0.4mm}{black!60!white},
    overlay={
        \fill [fill=brown] (frame.south west) -- ++(7pt,0) -- ++(0,-5pt) -- cycle;
        \fill [fill=brown] (frame.north west) -- ++(7pt,0) -- ++(0,5pt) -- cycle;
        \fill [fill=brown] (frame.north east) -- ++(-7pt,0) -- ++(0,5pt) -- cycle;
        \fill [fill=brown] (frame.south east) -- ++(-7pt,0) -- ++(0,-5pt) -- cycle;
    },
    after={\vspace{10pt plus 1pt}\noindent},
    #1
}

\begin{document}
\lipsum*
\begin{paperbox}[width=200px]{lipsum}
\lipsum
\end{paperbox}
\end{document}

How do I go about doing it?

Answer 1

One alternative to multicol could be cuted:

\documentclass[a4paper,twocolumn]{article}
\usepackage{cuted,tcolorbox,lipsum}
\begin{document}
\lipsum[1]
\begin{strip}
\begin{tcolorbox}[title=A tcolorbox]
    \lipsum[2]
\end{tcolorbox}
\end{strip}
\lipsum[3-6]
\end{document}
