Size: 150 Purchased on Amazon for around 3000 yen. New, unused condition; only tried on over underwear by a slender child who usually wears size 140. I don't think we'll have a chance to use it, so would anyone like it? As a bonus, I'll include unused beach socks (300 yen item from Daiso). *Please provide your immediate purchase price for price negotiations. *Instant purchase is welcome◎
