The technology disclosed herein includes a packaging apparatus including an outer sleeve, an inner sleeve, and at least one locking mechanism configured to lock the inner sleeve inside the outer sleeve. In some implementations, the locking mechanism is an interior sliding mechanism, which locks the inner sleeve in its entirety in the outer sleeve. In some implementations, the locking mechanism is an interior sliding mechanism, which permits the inner sleeve to move partially out of the outer sleeve. In some implementations, the locking mechanism includes a spring, a tab, a flap, a key, a magnet lock, or other locking component. In some implementations, the inner sleeve includes a pull tab for removal of the inner sleeve from inside the outer sleeve.
