As Google Inc's Android operating system enters China's smartphone market, its second-generation Google Glass device is attracting interest from Chinese consumers days after a brief one-day sale to the general public.

Chinese online sellers are skating into the Glass market in a bid to sell more gadgets in a country where official purchase is not available.

On Taobao, the Chinese version of eBay, nearly 70 sellers are offering authentic Google Glass devices priced between 12,000 yuan ($1,930) and 30,000 yuan.
