★ Size can be adjusted, but it's a good fit for people with smaller heads.
★ It's free size, but I think it might be a bit too tight for people with larger heads.
★ Purchased on Amazon last month for ¥3,500.
★ I bought it as a gift for a family member, but they don't use it (never used), so I'm offering it to someone who will.
