Scared your thumbs might be too tiny to handle the iPhone 6 Plus or other huge touchscreen devices? A new product from Japan is here to help.

Tokyo-based gadget company Thanko Inc. has created a thumb extender that makes it easier to navigate screens on large phone-tablet hybrids, known as "phablets." The company originally created the device, which it calls the "Yubi Nobiiru," back in May, and it seems to work pretty well.

Activities we would not recommend while wearing the thumb: wearily massaging your eye sockets, tying shoelaces or holding babies.

The mega thumb addresses complaints that phablet screens are too big to navigate with just one hand. Some have even said that the 5.5-inch screen on the iPhone 6 Plus is causing "thumb stretch" for men and women alike.

So how does the "Yubi Nobiiru" work? It's primarily made of silicone and has a conductor on the edge of the thumb that allows you to manipulate your screen, according to The Wall Street Journal.

In a video posted to YouTube, which you can watch above, the company demonstrates that its extender is particularly handy when you're riding on public transportation and have to use one hand to hold on. That's when you should attach the big, fake plastic thumb to your other hand for an extra half-inch of smartphone-tapping pleasure.
