Product IntroductionA wedding gift item pen shape USB drive made of metal and leather with stitching on the leather part, increase comfort and reduce fatigue of holding pens. USB memory is able to be taking out from top but does not influence the effect of stylus itself.

Including strong, long-lasting metal clips for portability, these custom pen USB drives merely pop out from the top, exposing easy-to-use flash drives.
