Apple said it has re-opened all its 270 U.S. stores, the first time in almost a year after it was forced to shut down several retail outlets because of the COVID-19 pandemic.

The iPhone maker has been cautious in re-opening its retail stores, using a team that includes medical experts to make its own calls on a county-by-county basis and sometimes shuttering stores again when local rules would otherwise allow stores to operate.

The iPhone maker has also expanded its Express format, a wall built in front of the main store with sales counters protected by plexiglass and a few shelves of accessories such as phone cases and AirPods.
