You hide a chest on the Ethereal Plane. Touch the chest (3 ft × 2 ft, 200 lbs) and a tiny replica of it; the chest vanishes. While holding the replica, use an Action to recall the chest to a space within 5 ft of you, or send it back. The chest is hidden for 60 days; after that, there's a 5% daily cumulative chance it is lost.

Material: an exquisite chest worth 5,000 gp and a Tiny replica worth 50 gp
