cusp-pen / Stationery

We often need to cut a piece from paper after writing something. But without knives it is often difficult to make it quick and clean. This CUSP-PEN has a rigid plastic cusp at the end of the pen, which can carve a crease line on the paper and pull the paper apart with easiness, just simulates the human manner of folding papers before tearing. Meanwhile, CUSP-PEN is one-piece-formed product and will not be dangerous because of its blunt edge.
