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

I gifted a friend who gave birth last year this Avent Natural Glass Baby bottle because she's against plastics, BPA etc. I got it here for about 19SGD. http://www.philips.com.sg/c-p/SCF671_17/avent-natural-bottles-natural-glass-baby-bottle It is made out of pharmaceutical grade glass, BPA free and easy to clean. My friend was delighted with it!
