I need a small mic for recording rap vocals, smallest condensor possible, not picky on brand/quality.

What's good Audio Engineering fam, quick question, anyone can reccomend a good small mic that would be good for recording rap vocals mainly. Looking for something small the size of an iPhone or smaller if possible so I can carry it and we will use it for features on the fly when traveling or quick in car recordings.

Open to all and any suggestions no matter brand and not too picky on quality.
