Google is offering some members of its Glass explorer program the chance to purchase a second pair, as noted by Glass Almanac.

The company announced an update to its prototype hardware in October, allowing explorers to swap their old versions for new ones. Now, it’s allowing them to keep their first and buy a second unit, which they can also give to a friend. Google launched its Glass accessory store in late October.
