1/4 inch (6mm) Sprial Bones sold by the Piece
Spiral bones are the most flexible of all bones; offering some support but some freedom of movement as well. The manufacturer is converting from "capped" ends to "dipped" ends so you may end up with both if you order more than one size. The manufacturer does not guarantee exact lengths. The lengths may vary as much as 1/8" (3mm).
