We compute the masses, decay constants and gluonic matrix elements on the $\eta$ and $\eta'$ mesons in lattice simulations across four lattice spacings with the light quark masses reaching down to the physical point. A comparison is made to the Large-$N_c$ chiral perturbation theory (ChPT) predictions and the NLO low energy constants are determined.
