World Cage - Display Jonna (including tester) This display is perfect to present the cages from World Cage in your store. This brand offers chastity devices in three sizes as well as complementary accessories. The big difference with other chastity devices is the fact that these cages are made of ABS plastic instead of polycarbonate (which contains plasticizers). In addition, the set includes 5 different rings, ranging in size, so there's no need to buy expensive add-ons. Lastly, the silicone security shield will make it impossible to escape the chastity cage.
