Later, red, blue, grey and black options were available but there were no reports of the 1500 USD Google Glass sales site crashing or customers being asked to leave the website, said reports.
The firm said it mostly sold white Glass models."Wow, what a morning! We are happy to see so many new faces (and frames) in the Explorer Programme," Google posted on a Google+ page, announcing the unavailability of the 'Cotton' model.
According to a Google post, "We have got a limited number of spots available, so do not wait too long - we can't wait to meet you and hear about your first adventures with Glass".
There were no queues outside Google buildings as the eyewear was only available online. Google has indicated that the mass-market version of Glass would sell for less than 1,500 USD later this year.
