This is a set of two NUK plastic baby bottles. I received these as unused items and opened them, but I haven't used them at all because I'm using other baby bottles. * Premium Choice Slim Baby Bottle (Polypropylene) Airplane 250ml * Premium Choice Baby Bottle with Temperature Sensor (Plastic) Giraffe 300ml The Airplane bottle has a size M nipple. The Giraffe bottle has an inner lid. Shipping is planned via Yu-packet Plus or Takkyubin Compact. ★ Individual sales are possible, but most of the cost is shipping, so the price will be 999 yen per bottle.
