It's just an old storage unit I use to keep stuff that doesn't fit in the van. If it's anywhere, it's in here.
|—Greg Universe, "Laser Light Cannon"|
U-Stor is a storage center where people can rent a storage unit to store their belongings in.
Greg used the unit to store a large number of items that didn't fit in his van. These items included a T-Shirt Cannon, a painting of a cat, a lamp, stacks of newspapers, a giant fish, a giant hat, some chess pieces, a boom box, a chair, a giant bottle, a lance, two mattresses, a drum, a fishing rod, an umbrella, a pool table, golf clubs, Li'l Butler VHS tapes, a T.V., a pet carrier, Rose's Laser Light Cannon, a picture of him and Rose, and more.
Steven, Greg, and Amethyst tried to clean out the storage unit, but the latter two ended up watching Li'l Butler instead and became addicted to the show once again. Later, with the help of Pearl and Garnet, the entire unit is cleaned out, with most of the items transferred to Amethyst's Room.
