After our arrival at ZZZ1 we were scheduled for 3-hours of standby duty at the FBO.  During that time someone; presumably the line crew; installed gear pins with narrow white ID-style neck lanyards used as flags in all 3 landing gear.  The flag (lanyard) on the nose-gear pin was especially problematic because it was only about an inch or 2 longer than the gear door and the white color made it extremely difficult to see.  The lightweight construction of the lanyards could also make them susceptible to being blown up into the gear wells rendering them invisible to the flight crew.Line service must notify the flight crew when they're installing gear pins and the flags used must be replaced with standard large red 'Remove Before Flight' flags so that they are more visible to the crew should they not be notified that the pins are installed.
An EMB-505 Captain reported that the line crew at the FBO he was parked at used gear pins that were non-standard and difficult to spot on a walk-around.
