This is an attachment for Meiji Hohoemi milk cans. When attached to a Meiji Hohoemi milk can during outings with your baby, it allows for immediate feeding, making it very convenient. I've used it a few times, but I no longer need it, so I'm putting it up for sale. I ask for your understanding as this is a used item. Please purchase if you are okay with a used item. I will wipe it down with alcohol before shipping. This is a set of 2 attachments. Normally, on Amazon, it costs about 530 yen each, excluding shipping. ⚠︎ Liquid milk and the attachment box are not included.
