This is a set of baby underwear that my daughter, born in late February, wore. It's a used item, but it's clean and still wearable. I gradually purchased these, so there are items for summer and winter. This set can be used for a year. Size: 70-80 Brands: Nishimatsuya, Birthday, Petit main (Please check the images for the brand and size of each piece of underwear.) I think this size is recommended for babies born from winter to spring, around February to May. It will be shipped compressed.
