City Storage Group’s BIG BOX MOBILE shipping container store provides portable storage units for rent or purchase. We deliver the bins to your location for you to pack with contents for moving or storage. Leave the bin on a trailer for quick moves or keep it on site as long as you need. When you finish packing, we can pick them up to transport back to our secure storage site or another location of your choice. For long-term storage, we offer shipping containers for sale.
