A poorly made chastity device is more than uncomfortable. It can cause skin abrasions, pinching, swelling, and even dangerous circulation problems. Cheap materials may contain irritants or rough seams that break down with wear. If you are going to lock up, invest in a body-safe cage made from medical-grade silicone, stainless steel, or another non-porous material. Proper sizing matters just as much as material. Measure carefully and adjust as needed. Your Domme deserves a device that is secure, safe, and not one that ends in pain or an urgent care visit.
