Choosing a chastity cage is, first and foremost, a matter of measurements: a millimetre too many or too few can turn a desired experience into immediate discomfort. This comparative guide walks you through the two decisive criteria — sizing and material — so that your choice is as informed as it is reassuring, whether you are discovering chastity for the first time or refining an already established practice.
Why is size the first criterion to get right?
A poorly fitted cage carries two opposite risks: too large, it slips and fails to serve its purpose; too tight, it causes circulatory discomfort. Before any purchase, two measurements are essential.
- The cage length: it should correspond to the flaccid length of the penis, without leaving excessive empty space or compressing the glans.
- The base ring diameter: this is the most critical measurement. Take the circumference at the base (penis and testicles together) in centimetres, then divide by π (≈ 3.14) to obtain the ideal diameter. If in doubt between two values, choose the larger one and test it without locking.
Almost all models in the Addicted Toys Locked catalogue include several rings in the same box to make this adjustment easier. Here is how the available diameter ranges are distributed across the range.
Comparison table: cage length and ring range
- Forbidden Vault — 75 mm cage, Ø 35 mm, 5 rings: 35 / 38 / 43 / 45 / 49 mm — the widest range in the collection, ideal for first attempts.
- Obsidian Hold (M) — 95 mm cage, Ø 34 mm, 5 rings: 35 / 36 / 42 / 45 / 48 mm — greater length, two very close diameters at the lower end of the scale for fine-tuned adjustment.
- Midnight Cell S / M / L — 86 / 95 / 100 mm cage, Ø 31 / 33 / 33 mm, 4 rings: 48 to 54 mm — the only range available in three distinct cage sizes.
- Chained Hollow — 105 mm cage, Ø 32 mm, 4 rings: 50 to 58 mm — the longest cage in the catalogue, suited to larger anatomies.
- Unbroken Den — 98 mm cage, Ø 30 mm, 3 rings: 50 / 52 / 58 mm + base ring — the lightest in its category (144 g as shipped).
- Sealed Crypt — 55 mm cage, 4 rings: 40 to 52 mm — the shortest cage in the catalogue, for the most compact anatomies.
- Silent Keep — 58 mm cage, 75 mm overall length, 4 rings: 40 / 42 / 48 / 52 mm — the lowest overall dimension in the catalogue, for maximum discretion.
- Chastity Depths — 75 mm cage, continuously adjustable ring from 35 to 52 mm — no pieces to swap, a 17 mm range covered by a single ring.
- Keyless Restraint — 75 mm cage, Ø 30 mm, 2 listed rings: 45 / 50 mm — the finest spacer adjustment in the range (12 spacers), shell-shaped cage.
- Iron Cell (M) — 75 mm cage, Ø 36 mm, fixed ring 45 mm — metal construction, 276 g, single non-interchangeable ring.
- Silver Lock (M) — 86 mm cage, Ø 46 mm, fixed ring 50 mm — the widest cage in the catalogue, deadbolt lock.
- Gilden Cage — 75 mm cage, Ø 36 mm, fixed ring 45 mm — 206 g (70 g lighter than the Iron Cell), material claimed by name but not confirmed by the manufacturer.
- Eternal Lock — 67 mm cage, Ø 31 mm, 4 rings: 38 to 52 mm, urethral dilator 20 × 4 mm — the only cage to incorporate a dilator.
Golden rule before locking: wear the cage without closing the padlock for at least one hour. Should any redness, numbness, or discomfort appear, remove it immediately.
How do the materials truly differ?
The Addicted Toys Locked range illustrates three material families found on the market — resin / polymer, metal, and a silicone-claimed material — with varying degrees of transparency depending on the product.
- Resin / polymer: most cages in the range fall into this category. The manufacturer does not specify the exact material for the padlock models (Forbidden Vault, Obsidian Hold, Chained Hollow, etc.). This type of material is lightweight, often translucent or tinted, and can be cleaned with warm water and mild soap or a dedicated sex toy cleaning spray. It tolerates everyday temperature variations well.
- Metal: the Iron Cell (276 g) and the Silver Lock (226 g) are the only products whose material is clearly stated in the product name. Metal offers absolute rigidity and easier maintenance, though its weight becomes noticeable over time. The Silver Lock's ring is 14 mm thick — almost double that of the Iron Cell (8 mm).
- Ambiguous material (Gilden Cage): the name suggests silicone, yet the specification block reproduces the Iron Cell's dimensions word for word. At 206 g — 70 g less than the Iron Cell for the same dimensions — the material appears lighter; the manufacturer offers no clarification.

Which models suit beginners, and which suit experienced users?
If you are new to chastity, opt for a cage with several interchangeable rings and a medium cage length: the Forbidden Vault (5 rings, 35–49 mm range) and the Chastity Depths (continuously adjustable ring) are the two most accommodating options for fine-tuning through trial and error. For a broader introduction to starter accessories, our article Which sex toy to choose as a beginner lays the groundwork common to all accessories.
For more experienced users looking to refine their comfort: the Keyless Restraint and its 12 spacers offer the most precise adjustment in the range. Metal models (Iron Cell, Silver Lock) suit those seeking the sensation of weight and total rigidity, provided they have already confirmed their ring size on a polymer model.

Hygiene and care: what the practice demands
As the cage is worn in prolonged contact with the skin, hygiene is non-negotiable. A few key principles to keep in mind:
- Clean the cage before and after each wear using an unscented mild soap or a sex toy cleaning spray.
- Dry the inside of the cage thoroughly before putting it back on.
- Inspect the skin each time you remove it: any persistent irritation should prompt a break and, if necessary, medical advice.
- Models with an internal lock (Sealed Crypt, Silent Keep, Eternal Lock) leave nothing protruding from the cage once closed, which limits friction points but makes a quick removal slightly less immediate in an emergency.
FAQ
How long can a chastity cage be worn safely?
No recommended wear duration is published by the manufacturer for this range. The universal precautionary rule applies: begin with one hour, remove the cage, and inspect the skin. Gradually increase the duration only if no discomfort is observed. If you have any doubts about your medical suitability for this type of wear, consult a doctor before extending sessions.
How do I measure my base ring size accurately?
Use a flexible tape measure or a piece of string that you then measure flat. Wrap it around the base of the penis and testicles in a flaccid state. Divide the circumference obtained (in mm) by 3.14 to get the approximate diameter. Compare this with the rings included in the box and always test without locking first. If you are torn between two sizes, go for the larger one.
Metal or polymer: which material is more comfortable for beginners?
Polymer cages (resin, plastic) are generally recommended for first experiences: they are lighter, less sensitive to temperature changes, and allow ring adjustment without the constraint of added weight. Metal — Iron Cell (276 g) and Silver Lock (226 g) — delivers greater rigidity and a more intense sense of restraint, but requires having already confirmed one's ring size and cage length on a lighter model.
What should I do if the cage causes discomfort or numbness?
Remove the accessory immediately. Numbness signals vascular or nerve compression that should never be ignored. Allow the skin a few minutes to recover. If the discomfort persists after removal, consult a healthcare professional. Only resume the practice with a larger ring diameter or a longer cage, depending on the area affected.
Are cages with a urethral dilator suitable for beginners?
No. The Eternal Lock is the only model in the range to incorporate a urethral dilator (20 mm long, 4 mm in diameter). This type of accessory requires prior familiarity with urethral dilation and strict hygiene. Consult a doctor before any urethral practice if you have a urological history or any doubts about your anatomy.
