Invisible Lock Series – Extra Short – 0.71″ (18mm)

Description

In the second half of 2025, we have upgraded some of our classic chastity designs. The lock has now been repositioned on the top of the device for improved comfort and aesthetics. At the same time, the base ring has been carefully refined to better match the natural body shape. Instead of traditional round or curved rings, the new arc ring design features a wider horizontal diameter than vertical, ensuring maximum comfort. It provides a snug fit without pressing on the testicles, reduces the risk of pinching, enhances stability during movement, and evenly distributes pressure for long-term wear.

The Invisible Lock Series includes four cage lengths: 0.3″ (8mm), 0.7″ (18mm), 0.87″ (22mm), and 1″ (24mm). These subtle differences allow you to choose the perfect fit for your training needs, or gradually progress to shorter cages as you advance — from flat to inverted.

Each device weighs only 18g–22g, making it lightweight, smooth, and comfortable for extended use. Finished in a matte texture, the cages are discreet, elegant, and premium in appearance.
