This is a set of 10 undershirts from Nishimatsuya! I used these for my twins! The heart pattern is cute, and they were worn a lot! I couldn't bear to throw them away, and I thought maybe they could still be worn, so I'm putting them up for sale! They've been soaked in Oxiclean and washed! But there are some stains! ☆ Newborn Undershirt 10-piece set ☆ ・ All-season material ・ 100% cotton ・ Lots of undershirts needed for babies who sweat a lot! ・ Perfect for regulating baby's body temperature! ・ Easy to put on and take off, with snap buttons that don't come undone easily ・ Includes 5 combination undershirts! ・ Inner ties allow for adjusting the width ・ Partially sewn on the outside, with external tags ・ Seams don't directly touch the baby's skin, providing gentle comfort ・ Made in China
