Miki House Newborn size 50 A set of 4 items: short undergarments and combination undergarments(^^) I've used other brands of undergarments, but Miki House's undergarments are 100% cotton and feel good on the skin, and are recommended for babies with sensitive skin♪ They have been washed with oxygen bleach (OxiClean) after use, so I think any unseen dirt has been removed. There are fold marks because they were stored folded. Please understand. I hope you have a wonderful encounter(^^) A size 60 set is also on sale♪ Long undergarment
