This neck adaptor fits a Titans Return neck port and features a 6mm ball joint on the end. It's suitable for many figures, but is intended for use with the "Large" size versions of my
Nautical Femmebot Head and
Nautical Femmebot Visor. The ball may be slightly loose and require thickening with clear nail polish or similar, this is due to inconsistencies with nylon printing affecting the tolerences.
