• What penis size typically fits this device? +

  This cage generally fits users with a flaccid length of 2–4 inches (5–10 cm) and a girth of up to 4.5 inches (11.5 cm) comfortably. The inner diameter of the cage (35 mm) accommodates most average-sized penises when soft. Because chastity cages are worn when flaccid, the key factors are: Flaccid girth — needs to comfortably fit inside the 35 mm inner diameter Flaccid length — should sit fully inside the 85 mm cage without bunching or pinching Shrinkage — if you “turtle” naturally, an open design like this is ideal because airflow prevents discomfort If you’re unsure, this model is considered one of the most forgiving fits because of its open metal frame, making it suitable for first-time wearers and most average-size users.

• Can I wear this device discreetly under clothing? +

  Yes. It’s lighter and lower-profile than many metal cages, making it suitable under most underwear and trousers. Tight clothing may show a slight outline.

• Is this cage suitable for long-term wear? +

  Yes. The open-frame design improves airflow, reduces sweat build-up, and prevents chafing—making it far more comfortable for extended wear than enclosed metal cages.
