Aimed at iPhone designers, we think this iPhone stencil may find its way into the stationery kits of fanatical fans too.

The Design Commission that sells the device says: "Quickly sketch out iPhone UI prototypes. Brainstorm your application ideas using our precision cut stainless steel stencil and mechanical pencil".

Complete with Zebra mechanical pencil, the metal stencil is available internationally for $16.95, plus shipping.
