Initial softball necklaces are listed with an 18" chain plus a 2" extender for adjustable fit. The initial pendant is reported at about 15 mm long by 11 mm wide.

Descriptions highlight nylon (and some titanium components) for a soft, comfortable feel and a durable construction that resists deformation and is comfortable against the neck.
