I stopped carrying my pens simply because I kept losing them.  The Slimmy Front Pocket Pen fits perfectly on your Slimmy so you know where it is all the time.  Unlike most pocket pens, this one expands from 3.5" to a full 5".  This little pocket rocket feels substantial despite its size, writes beautifully and is rather good looking.  If you are looking for pen that does not require a shirt chest pocket, look no further.  You are going to love the Slimmy Front Pocket Wallet be Zebra.
