You can easily open each collar in a natural way with pose controls.
MORPHS
The collars also have some morphs, allowing you to tweak the spikes, so you can come up with even more collar variations.
* 2 collars with straight spikes (Straight and Straight Enhanced) have width and length spikes morphs.
* 3 collars with curved spikes (Crowny, Crabby, Sawtooth) have just overall spikes size morph.
* 1 collar with double spikes (Double-Spiky) has no morphs.
