This 3-inch-long gold chain has a clasp on each end.

A wilding clasp can be attached to any item worn on the body. When so worn, a clasp prevents the worn item from melding into your new form when you use wild shape (as long as the item could reasonably be worn by the new form). Thus, the item remains fully functional and can be used normally in your new form.

Prerequisites: Craft Wondrous Item, wild shape.
Cost to Create: 2,000 gp, 160 XP, 4 days.
