Your Voice Recorder Pen is here, it's easy to use, just push button On to record and Off to stop. Good for taking notes and reviewing later, the pen will do the job where phones are not allowed. It has a 16GB capacity which will store 100 hours of voice recording. It has built-in earphone jack and comes with a pair of earphone so you can listen to the recording right from the pen itself. It can also write like all pens do, which makes it 2 in 1 function.
