Summary:The utility model relates to a pen, in particular to a pen whose handwriting can be faded and become invisible. The utility model comprises a pen cap, a pen head component, a pen cavity and a penholder, etc. The pen head component is arranged on a front end of the penholder, which comprises a hard foam pen tip and a volatile ink storing sac, and the volatile ink storing sac is arranged inside the pen cavity. The hard foam pen tip can effectively absorb the organic volatile ink, therefore the handwriting can be faded and become invisible after some time due to volatilization of the ink. A back end of the penholder can be additionally provided with a conventional pen head component which can be a fountain pen tip, a ballpoint pen tip or one type of other common pen tips, therefore one pen has multiple purposes.
