Source: bioionic.com (verified 2026-07-10) · corroborated by underyours.com. The official bioionic.com OnePass Styling Iron product page confirmed this exact 1-inch model (Options: 1-inch) and listed "Final price: $217", digital temperature control "Upto 450°F", "Automatic Shut-Off Time: Yes (60 min)", "Universal Voltage: Yes" (dual voltage), a "Swivel Cord: Yes" with 9ft cord (so corded), and "advanced ceramic plates". The Under Yours retailer page corroborated the exact 1-inch OnePass model with "Digital temperature control up to 450°F/230°C" and a 9 ft cord; its listed $437.80 is an inflated dropshipper price and was disregarded in favor of the manufacturer's $217 (Boss Beauty Supply independently names the "Bio Ionic OnePass 1\" Straightening Iron" with "Universal voltage", further confirming identity). heat_settings is null because both pages describe a continuous digital/adjustable temperature control (with last-temperature memory) rather than a discrete preset count, and no fetched page states a launch year, so releaseDate and release are null.
