"The Thor" is a lightly spiked 2 inch double layer collar. This collar was designed for a handsome Malinois who looks tough but is a total softy, hence only a few spikes and a few decorative rivets :)

You can choose the color for both layers of biothane; Primary being the 1.5" top layer, Secondary being the 2" back layer.

You can also choose the color of the hardware, spikes, and decorative rivets.
