Built from high-quality PVC, it combines a substantial 5cm width with precision engineering to deliver both psychological impact and physical security. The collar's six-point adjustment system accommodates various neck sizes while maintaining consistent tension, and its 40mm O-ring serves as a universal anchor for leads, chains, and additional restraints.

What sets this collar apart is its dual thickness options and ergonomic design. The 2mm version suits those exploring bondage, while the 2.5mm thickness appeals to experienced practitioners seeking more intense sensory feedback.

How to use a collars and lead

Measure your neck circumference before fitting. Unfasten the collar and position it around your neck, then use the six-point adjustment system to tighten gradually until snug but not restrictive. Secure each adjustment point firmly to maintain consistent tension. Once fitted, attach a lead or chain through the 40mm O-ring for immediate control during your scene.

For advanced play, experiment with different attachment points on the O-ring to create varied angles of control or to anchor additional restraints. The collar works seamlessly with suspension techniques, sensory play, and impact scenes. See the full BDSM Australia range of BDSM Leads to discover options that pair with your collar for layered control and psychological impact.

Clean the collar with mild antibacterial soap before and after use, dry thoroughly, and inspect regularly for damage; adjust only to a snug fit that allows comfortable breathing and doesn't restrict blood flow. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Clean your collar after each scene with mild, non-abrasive antibacterial soap and warm water. Dry completely before storage to prevent mildew or material degradation. Store in a cool, dry place away from direct sunlight, extreme heat, or sharp objects. Inspect the PVC and O-ring regularly for cracks, discoloration, or wear, and replace if damage occurs.

Mistress Athena's training notes

This collar has become my primary instrument of control in training sessions. The six-point adjustment allows me to calibrate pressure with surgical precision, observing immediate physiological responses—quickened breathing, subtle muscle tension, pupil dilation. My submissives register the psychological weight of each adjustment point, and I use that awareness to deepen their surrender.

The 40mm O-ring transforms into my direct conduit of command. By varying attachment angles and adding leads or chains, I create different sensory experiences and redirect attention instantaneously. The 2.5mm thickness proves invaluable with experienced slaves who require more intense input; the thicker material demands respect and delivers unmistakable sensation.

What fascinates me most is how the collar becomes a map of psychological boundaries. Each adjustment point represents a threshold I systematically explore and expand. Some submissives respond to gentle tension and the collar's visual presence alone; others require aggressive positioning and sustained pressure. The versatility of this design allows me to customize every interaction.
