Vanish

An object you touch becomes invisible until the spell ends. The object must be no larger than a 10-foot cube. If the object is a closed container, any object that is fully contained within the object is also invisible as long as it is within the closed container.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the spell lasts 24 hours, without requiring your concentration. When you cast this spell using a 9th level spell slot, the spell lasts until dispelled, without requiring your concentration.
