Here’s what consumers have asked with answers from Mizonworld staff and previous consumers.
Products are made in Korea, but mizon is present globally. American products will probiably be shipped from the physical mizon US location.
I've only ordered from them once, but my package came within a week and I got free US shipping after hitting their minimum purchase amount.
Packaging is standard and as expected. Nothing special: just some makeup items in a box with some wrap.
