After uplifting to massive type IIA supergravity these correspond to the near-horizon limit of a system of $N$ D4-branes and $N_f$ D8-branes wrapped on $\\mathbb{M}_4$. In one class of solutions $\\mathbb{M}_4 = \\Sigma_{\\mathrm{g}}\\ltimes\\Sigma$ is a spindle fibred over a smooth Riemann surface of genus $\\mathrm{g}>1$, while in another class $\\mathbb{M}_4 = \\Sigma\\ltimes\\Sigma$ is a spindle fibred over another spindle.
