Two couples, close friends who shared a two-family Brooklyn home, had finished a full interior renovation but still had an entrance lined with trash cans — plus package theft, no mail solution, and a folding bike with nowhere to go.

A CITIBIN estimate visit turned into the development of three new products: the ParcelBin package locker, a mailbox module, and an all-purpose storage box — all integrated into one modular system that kept both households’ trash, recycling, packages, and mail neatly separated and beautifully unified at once.
