Where can I get feeding bottles in glass (not plastic)

I had the Avent Natural Glass Baby bottles too and my son took it very well before switching to Comotomo. Alternatively from the website Idza has mentioned, you can get them at major departmental stores like Isetan, Takashimaya or kids' stores like Kiddy Palace or Mothercare. Otherwise you could grab them at babyfairs where they run really attractive promotions but the lines are usually snake long!
