My daughter attends Wednesday night Adventure League for D&D, and figured it was good way to give back to the store for hosting it, by buying 1-2 every Wednesday. I also think the models are pretty good, and would add some new poses to my collection. Wasn't aware that they are taller than classic marines and shorter than Primaris marines.
@paxmiles if you decide to start collecting them, I would be willing to swap duplicates if you are interested.
