How to Read Chastity Cage Product Measurements

Product measurements can describe different parts of a cage. A 50 mm ring is an opening; a 50 mm cage length is a body dimension. Before comparing two listings, identify what each number measures and whether the unit is millimeters or inches.

You can apply the measurement checklist to the Mamba 4.0 size range, checking each listing's exact definition of length and ring diameter.

Four labels to separate

• Ring inner diameter: the opening inside the base ring, usually compared with measured circumference divided by π.
• Overall cage length: the external body from the maker's chosen endpoints; it may not equal usable inside space.
• Usable internal length: the room available inside the body, if the seller states it.
• Internal width or diameter: space inside the cage, not the ring opening or outside width.

Apply the labels to a live listing

The Pink Mamba 4.0 Chastity Cage gives Nub 40, Nano 55, Small 72, Standard 91, and Maxi 107 mm listed cage lengths, plus 43, 46, 49, and 51 mm snap-ring inner diameters. The listing does not state every internal cage dimension, so do not relabel these lengths as guaranteed usable room. Ask for missing measurements when they affect your choice.

Use the Mamba size guide for the full measured method. Compare a selected variant and package, not just the family headline. A correct label prevents buying a ring-size change to solve a body-width problem.
