This is a set of German-made NUK Hello Kitty baby bottles purchased in Taiwan. They are rare because they are not available in Japan! Rest assured, these are licensed Sanrio products. The baby bottles are plastic and come in a set of two large (300ml) bottles. They come with nipples for babies aged 6-18 months. The nipples can be replaced with Japanese wide-neck nipples (like those from the "Bonyu Jikan" series). I am also selling Hello Kitty baby bottles and milk cases. (*^◯^*) Instant purchase is OK!
