Google released Google Cardboard in 2014.Google

Google Cardboard VR has been around for over two years now since it was unveiled at the Google I/O 2014 developer conference. Following its release, this inexpensive VR viewer that is made from a cardboard fold-out has been sold through third-party companies.

But now The Verge reports that Cardboard VR viewer can be bought directly from Google, via its online store. A single unit of Cardboard VR is being offered at $15 and users can buy a pack of two for $25.

The Cardboard VR kit will be compatible with any smartphone, which is less than six inches in size.

Apart from the Google Cardboard VR kit, Google is also selling Mattel View-Master VR Starter Pack, which "blends education with fun" and Goggle Tech C1-Glass VR Viewer, which is "made for VR adventures on the go."

The Mattel View-Master VR Starter Pack has a plastic exterior with a red paint and features robust lens. It is being sold at $29.99.

The Goggle Tech C1-Glass VR Viewer is almost the size of the pair of glasses and comes with microfibre bag that helps in cleaning and is easy to carry. This VR viewer is foldable and costs $14.99.

Predictions have suggested that Google VR tech is likely to play a bigger role in the upcoming Google's annual developer conference in May 2016.
