Season one “Small Curvy” on 1/6 (Soom, Violet), 1/4 (Dollmore, Zinna), and 1/3 (DF A, Dollism Practice). After this they get bigger and are less suitable for 1/6 scale dolls, at least as a pair (I’ll try straight spirals as a unicorn horn and see what happens). Again, the horns are stuck on with eye putty so the future owners can chose magnet polarity. Accept for Carver, those horns are his and do have magnets.
