Vehicle trim panel storage systems

A trim storage system for a vehicle includes a guide slot that extends along a longitudinal axis, and a guide including a first flange opposite a second flange. The first flange defines one or more first ribs that extend from the first flange, and the second flange defines one or more second ribs that extend toward a respective first rib of the first ribs to define one or more slots spaced apart along the longitudinal axis. A pocket is defined between adjacent slots of the slots. The trim storage system includes a fastener removably coupled to the pocket of the guide having an attachment portion configured to retain an item.
