Thank you for viewing. I purchased this at a store. It's Muji's navy leggings, 5-分丈 (five-part length). The original price was 790 yen. I've used it 2-3 times, and it was around the time when my child started moving around indoors, so there is some fuzzing and pilling. Please be aware that since it's navy, fibers and such may stick to it. It's not thin, so it seems suitable for indoor use in the fall and winter. For those who understand that this is a used item, thank you.
