Spirit Capturing Device

"A box used to hold captured spirits. It's specially enchanted so that once a spirit is placed inside, it cannot escape. A box used to capture one of the spirits that presides over the natural world of Granzelia must contain great magical power, but the precise nature of this power is unknown. How the box was made is also a mystery. Whatever the case, any spirit must be treated with the utmost respect when captured, unless the capturer wishes to provoke nature's wrath."
