8b + Manny chalk holder. The opening is rigid to ensure immediate access to the magnesium and the magnesium holder also has a slot for the brush. The interior is plush in order to retain as much magnesium as possible. Manny comes in a protective bag and is equipped with an adjustable strap and a snap hook to hang it from the harness. Fantastic idea for an out-of-the-box gift too! 8b+ 8BPLUS Chalk Bag Manny
