Product and safety information

Full safety and compliance details

Details

The complete SneakPen kit: a working ballpoint with a reading window in the barrel, the pocket printer that fills it, a roll of thermal paper and the fine tweezers that take a strip back out. Type your lines in the free SneakPen web app, print the strip with the free FunPrint app, fold 2 mm at each end toward the text, feed it into the two rollers and turn the wheel to bring the words past the window. Turn the cap and the window is covered: it is a plain black pen again, and it still writes. The size of a normal pen: 12 mm across and 152 mm long. Ships in a black gift box.

Anything you want at hand without reaching for your phone: the outline of a speech, a recipe, song lyrics, a packing list, a to-do list.

The questions people actually ask.

A real person reads and answers every message.

Ask us anything All questions
SneakPen or SneakPen Solo: which one is right for me?

Same pen, two ways to fill the strip. With SneakPen Solo, you cut the strip from the roll and write it by hand, following the cutting guide on our How to use page: 20 to 30 lines. With SneakPen, the pocket printer does the layout: every strip comes out already marked, up to 75 lines, and all that's left is to cut, fold and load it.

How much fits on one strip?

Up to 75 printed lines, or 20 to 30 lines by hand. A strip is 220 × 40 mm, with a 16 cm text zone in the middle.

Does the app work on my phone?

The SneakPen app runs in any recent browser, on iPhone, Android or a computer. FunPrint, the app that prints, is free on the App Store and Google Play. Setup on How to use.

Does the pocket printer need ink?

No, never. It prints with heat on thermal paper, so there's no ink or cartridge to buy, and it prints in black. The only refill is paper.

How long does delivery take?

It depends on your country: each one is listed with its delivery times in our delivery table.

Can I change my mind?

Yes. You have 30 days from delivery to change your mind, with no reason needed. Start from our Returns page. The full conditions are in our Terms of service.
