Retail price: 6600 yen (tax included) ※ This is type I! 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 a little color transfer on the white inside part due to friction. It's circled in the picture. You can use it during pregnancy and after childbirth ♪
