Lead-lined chest

This lead-lined chest is a small container lined with lead designed to block the radiation of Kryptonite.

Batman once used this chest to store the Martingale family's sky stone, which Marvin and Wendy ignorantly brought to show the Super Friends, not knowing it was Green Kryptonite, and therefore quite harmful to Superman.
