After coming to the U.S. Google Store in February, Cardboard VR units are now available to purchase in Canada, the UK, France, and Germany.

Available for $20 CAD, £15 and €20 in Canada, the UK and Germany/France respectively, the unit is the redesigned second-generation Google Cardboard. Google is also selling two-packs of the VR viewer for $35, £25 and €30 in each region.

Google notes that there are now "thousands of VR apps and games and a variety of captivating YouTube videos made to view with Cardboard," including Paul McCartney, New York Times, and Star Wars.

It's unclear whether Google plans to stock more versions of the Cardboard VR viewer; additional units, such as the Mattel View-Master VR and Goggle Tech C1-Glass VR Viewer, are for sale on the U.S. Google Store.
