this baby bottles is make from borosilicate glass, it is the same kind of glass used in laboratories, and it is also much lighter than traditional glass that is used for baby bottles.
i tried avent bottles before, i think this is better than avent bottles because avent does not make a BPA-free version bottles last time, but now there is and still recommended to change the bottle every 6 months.
you may get this product from justlife@Ikano Power Station
the silicone bottle wrap is selling separately, it comes with 3 colors, pink, green and blue.
