Dr. Brown's ナチュラルフロー 広口ボトル用 保管・旅行用キャップ 2個入り

These caps snap on so easily, and the wide neck means I can pour milk right in without any spills. The seal is solid too—I’ve thrown a bottle in my diaper bag on a bumpy walk and not a drop leaked.

Finally, no more fumbling with foil lids when I'm packing bottles for daycare. These caps click on tight enough that I can toss the bottle in the diaper bag without a single leak, and they're super easy to rinse out after a day of travel.

These caps twist on securely and create a tight seal, so I can toss a prepared bottle in my bag without worrying about leaks. They’re super handy for popping in the fridge overnight, too.
