For example, services that target the higher education populations offer drop off and pick up to college dormitories, and "micro self-storage" services offer less-than-full storage containers delivered to a residence. Some services provide customized cardboard or plastic boxes and/or packing materials as part of the cost, standardizing the boxes for optimal storage while adding a requisite waiting time for the packing materials and boxes to arrive. Other variants allow customers to self pack and send boxes directly to self-storage one box at a time (or as many boxes as needed) and offer to-the-doorstep delivery in another location, eliminating the requirement to pick up items in the same location as where they were stored.
