These are car key fob shells (also called key covers, key cases, or remote key housings).
They are protective outer cases designed to fit over (or replace) the original remote control key fobs for various cars. Most in the photo are off-white/cream-colored soft plastic (often TPU) with gold-colored trim and button icons for lock, unlock, trunk/boot, and sometimes panic or other functions. One is black with gold accents.
