physical stores for fountain pens & inks for swatching, ideally qc area?

hi! alam kong may scribe at everything calligraphy pero may mga iba bang options around qc? want to start buying bottled inks as kakakuha ko lang ng converter for a parker pen (ng lolo ko dati, not sure model) but online shopping is a pain where i live kase laging nawawala mga driver + prefer ko naman din lumabas labas pag may gustong bilhin for myself especially.

looking into trying diamine inks especially :3
