Meet the JTS S239, a flat-front chastity cage crafted from food-grade 304 stainless steel. Its polished, low-profile face and integrated sliding lock combine a distinctive reflective finish with a discreet shape. The durable, waterproof and rust-resistant steel is easy to clean and designed for hygienic use.
Choose a Circular or Curved base ring in a 40 mm, 45 mm, 50 mm or 55 mm internal diameter. You can order the cage alone or select an option with a waist strap, urethral sound, anti-shedding ring or the full accessory set. Check all three selectors—ring size, ring type and additional option—before adding your S239 to the cart.
Flat, Polished 304 Stainless Steel Design
The flat front is made for a streamlined look under clothing, while its polished surface gives the S239 its distinctive shine. Its carefully selected ring and low-profile shape are designed for comfortable, discreet wear during work, commuting and everyday movement. For exercise or other activities, check that your chosen size and accessory combination remain comfortable for you.
The front plate has a central opening and six smaller surrounding openings. Its accessible surfaces make routine rinsing and cleaning more convenient.
