Abstract: An adapter for pen, pencil, or any other types of writing instruments where the adaptor is sized and dimensioned to receive a regular sized writing instrument, and the adapter is designed for safety to use such writing instrument as a refill. The design has an inner holder designed to securely hold the writing instrument. In one embodiment, the adapter is short enough to expose a proximal end of the writing instrument, so that the exposed part of the writing instrument becomes a push button. In another embodiment, the adapter has a push button, and the regular sized writing instrument is entirely contained with the adapter. Other embodiments use different retracting mechanism such as twist-and-retract mechanism, and slider mechanism.
