>>9968213I just checked with my Ruroni Kenshin Qposkets and wedding topper Mei for Overwatch nenderoid heads and the peg is double sided but too small for the Qposket hexagonal hole and also much larger, I would actually suggest putting it on a bigger body but placing the head on with silly putty would keep it straight but overall they are huge compared to nenderoids.
Also not a fashion doll. Put it on a fashion doll body and it counts tho.
