The Annlary one-inch straightener uses titanium plates with a ceramic coating and eight heat settings from 320°F to 450°F. Its listing specifies 100–240V input, a swivel cord and automatic shutoff after 60 minutes, making it a practical travel option. The one-inch plate is slower on very long, dense hair than a wider iron.
