Seeing these a lot at ridiculous prices... The regular single blades and the double blades... One dispenser for anywhere from $18 to $50 US with an additional $10 to $20 US shipping cost. Are these that expensive in Japan? Like if I walked in a store in Japan to buy a pack, are they priced that expensive there too? For example, $25 US / 2,746 JP¥ Any Japan-based members here that could weigh in? Or anyone who has been to Japan recently and purchased these?
