I bought this in July of this year. It was sized M to L, with a waist size of 87 to 100, so I bought it without a second thought. But when I opened it, I was surprised – it was too narrow and wouldn't fit me. I've just been storing it since then. I think it would fit someone with a slimmer build. I've forgotten the manufacturer, but it cost 3,528 yen. I haven't used it, but I've had it stored for several months.
