You receive 4 different ring sizes when you buy a Vice chastity cage. But if those rings are still too small for you, this XXL ring might be perfect for you! The XXL ring has a diameter of 57mm and the XXXL ring has a diameter of 63.5mm.
Luckily you could order this ring size separately. Otherwise I wouldn't have been able to do anything with the Vice models.
It would be even better if you could also order the different cage sizes separately without having to buy a complete set.
