Is your smartphone too unwieldy for such tiny human hands? There's an artificial thumb for that.

With the larger iPhone 6 models, for one obvious example, phone manufacturers continue to increase the size of their handhelds. Japanese company Thanko has designed a finger extender to give you an extra 15mm of reach while handling these ever-growing devices. And the handy gadget is designed to resemble the human thumb.

The stylish (or disconcerting, depending on your taste) device can be yours for 1,480 yen, or about $14.

It makes sense that phablet manageability is on Asian manufacturers' minds: The region has a noted fondness for larger phones, and many have opted for the phablet devices in lieu of both a phone and a tablet.

Apple's iPhone 6 and even larger iPhone 6 Plus had a record-breaking launch, and Samsung's Galaxy Note 4, with a 5.7-inch display, is poised to launch in Korea later this month.

While our biological phalanges may no longer be enough to keep pace with the size of our smartphones, at least there's something to help.
