F.C.R.B, uniform experiment, and SOPHNET. brands are all represented in a series of promotional Pilot Frixion Pens. The SOPHNET. family take after fragment design in collaborating on this unique pen from Pilot, made for those of us needing a back up for our spelling mistakes. A selection of logos from the brands is used throughout, but in reality we’ll take any excuse to get our hands on this Pilot Frixion Pen.
