ToI: Greencloak's Compact Carrying Charm

You touch one object that is no more than 5 feet in any dimension, or a nonmagical object that is no more than 10 feet in any dimension. The object shrinks to be up to 1 inch in each dimension, and its weight changes appropriately. For example, if the object is now one tenth of the size it was, it is now one thousandth of the weight. The object retains other properties, like AC and hit points. When the spell ends, if there is not enough space for the object to return to its original dimensions, it will push any smaller objects or creatures in its path to an unoccupied space beside the item. If that is not possible, it instead transports to the nearest available space that can accommodate its size. You can end this spell early as a bonus action if you say the command phrase within 30 feet of the object, provided there is enough space for the object to return to its full size.

At Higher Levels. When you cast this spell at 5th level or higher, you can increase the dimensions of the affect object by 5 feet in any dimension, or 10 feet for a nonmagical item, per spell level above 4th. If the spell is cast at 7th level or higher, the duration becomes 7 days. If the spell is cast at 9th level, the duration is until dispelled.
