MUJI "Pump Head / Cotton Only"
Maybe it can be used for your own lotion?

Do you pick up the lotion used for skin care directly or do you put it in cotton?

I'm a cotton sect, but it's a little annoying to hold a bottle in one hand. What's more, the Naturie "Coix lotion" I'm using is only a large size (500ml (16.91us fl oz)), so it's quite heavy to start using ...

Speaking of the goodness of cospa, "Coix lotion" cotton pack can also be pounded

Meanwhile, I saw "Pump head cotton only" at the MUJI cosmetics corner. The upper part is like a plate, and you can easily soak it in lotion by attaching it to a bottle and pressing it with cotton from above. This is a convenient feeling!

Oh, this is ...!

However, the package says, "Use it with MUJI's lotion / cosmetic solution (200ml (6.76us fl oz), 400ml (13.53us fl oz) type)" ... But if you look closely, MUJI's bottle is not similar to Coix seed lotion?

That's why it fits perfectly when I put it on.

Be careful not to push it without cotton as it will come out quite vigorously

It could also be used for "Dub Wiping Water Cleansing" (235ml (7.95us fl oz)), which is also in use. The original pump head is too vigorous to jump over cotton, which is also helpful (tube length needs to be cut).

You can wipe it off immediately by pressing it with one hand.

When I measured it, each bottle had a mouth diameter of about 20 mm . In addition, there is a certain amount of capacity so that it will be stable when pushed from above.

For your information

By the way, if you really want to use your own lotion for this pump head, you can transfer it to MUJI's "Polyethylene Refill Bottle One Touch Cap (250ml (8.45us fl oz) / 400ml (13.53us fl oz))".

It doesn't seem to be a special standard, so there are likely to be more bottles that can be used. Not only those who use the same products as the author, but also those who are cotton enthusiasts who wondered, "Well, maybe it's good for your bottle?" The price of the pump head is 350 yen (tax included). It's not cheap at all, so be very careful.
