There’s more that can be done with your phone’s headphone jack than meets the eye. First and foremost, it’s where you’re supposed to plug in your earphones or headset so you can make and take calls hands-free and listen to some music. It’s also where people put phone jack charms and accessories in order to bling up their devices.
And then there’s the Jackpen. It’s a miniature pen that fits into your smartphone’s headphone jack, transforming your device into a pen of sorts. When you’re done using it, just flip the pen around so that the non-writing side is what’s facing the outside.
A pack of three Jackpens costs £3.99 or about $7.
