Over the years, Apple has included a SIM-eject tool with iPhone and iPad models with a SIM (Subscriber Identity Module) tray. Early Apple SIM eject tools were more substantially designed than this version and were made from an alloy named Liquidmetal.
This version of the SIM eject tool shipped with an iPhone SE (2017). While a previous version of the tool was solid, this SIM eject tool is essentially a bent wire. It is unknown as to whether this tool is made from Liquidmetal.
Interestingly, Apple’s official Support web pages refer to the “official” SIM-eject tool, but picture a bent paper clip in their how-to diagrams for removing SIM cards.
