Retail price: 6600 yen (tax included) I bought this during my pregnancy and used it a few times over an undershirt, but I mostly just stored it away. I think I used it for less than a week ^_^ There's no wear and tear on the Velcro, and it hasn't stretched out. There's some color transfer from friction on the white inside part. It's circled in the picture. Can be used during pregnancy and after childbirth♪
