Boum-Boum Milk - 200 ml

Just poured it into my regular bottle and it fit perfectly—no mess at all. I love that one 200ml refill can top up a travel bottle four times, which makes it perfect for my weekend bag.

Finally, a refill that actually fits the bottle without spilling everywhere — the 200ml size is just right. I've already used it to top up my travel bottle twice, and it's saved me from buying a whole new plastic container. Really happy with how simple and waste-free this makes things.
