Fluffing a Hard Pillow

Taking the two boxes off the table, Di Tou raised a palm and tried to put them into his Spatial Ring only to fail. Stunned, he took a few moments to react before recalling how the bowls had shrunk into the boxes. Smacking his head, he couldn't help but lament that he had overlooked such a simple detail. As Spatial Devices themselves, the boxes wouldn't so easily be contained in another Spatial Device like his Spatial Ring. Although it wasn't impossible for this sort of overlay to occur, it would need a much more advanced or high-quality construction, either on the part of the boxes or the ring.
