## Description

4 x Medella Breast Bowl Harmony Parts O-Rings Aftermarket BPA/DEHP Free Silicone Rubber Includes 2 bonus white membranes. Made in Taiwan

Review: 不安だったけどピッタリでした！ - 搾乳機の圧が急にかからなくなって、調べるとOリングが紛失してることに気付きました。 公式サイトやフリマサイトにも出品されてましたが、発送まで時間がかかりそうなのと割高だったので、日本語レビューが１つしかなく不安でしたがこちらを買ってみました。 写真にあるようにわずかに隙間はありますがちゃんと圧がかかるようになりました！ 同じように紛失した方にオススメです！ 付属のフタは写真だと穴が空いているように見えましたが、実際は穴はなく、純正と全く同じ感じでちゃんと接続もできました。
Review: ポロッとなくしやすいので必須 - この部品がないと吸引ができないのに、寝ぼけて洗浄していると気が付いたら無くなっている。買っておいた方が心情的に安心です。
