Explore a snug, stretchy fit with the XR Master Series Annex Super Stretchy Erection Enhancer. This clear TPR accessory combines a penis ring with a distinctive T-style ball separator for a close-fitting design that can add a different sensation to solo or partnered play.

The stretchy construction is designed to accommodate a range of body sizes, although individual fit and comfort will vary.

Use & Care
Checking the Fit
The main ring measures 1.25 inches across when unstretched, while each opening in the T-style separator measures 0.75 inches across when unstretched.
Because the manufacturer does not specify maximum stretch dimensions, these measurements do not guarantee compatibility with every body size.
Choose a fit that feels comfortable without excessive compression. Do not force the device into position or continue wearing it if it feels too tight.
Using the T-Style Ball Separator
The integrated separator is designed to create individual openings around the scrotal area.
Scrotal tissue is sensitive to pressure and can be injured by excessive stretching or compression. Handle the material gently and avoid pulling or twisting it against the skin.
Do not use the device if you cannot remove it promptly and comfortably.
Circulation & Wear-Time Safety
Erection rings work by restricting blood outflow, which can create risks when pressure is excessive or prolonged.
Limit wear to no more than 20–30 minutes, and remove the device sooner if you experience pain, numbness, tingling, swelling, coldness, or changes in skin colour.
Never sleep while wearing the device. Do not use it while impaired by alcohol or other substances that may reduce your ability to notice discomfort.
Consult a healthcare professional before use if you have a circulatory condition, reduced genital sensation, a bleeding disorder, or take blood-thinning medication.
If the device becomes stuck or you cannot remove it safely, seek urgent medical assistance.
Lubricant Compatibility
The manufacturer states that this TPR accessory is compatible with both water-based and silicone-based lubricants.
A small amount of compatible lubricant may help reduce friction during positioning and removal. Avoid using so much lubricant that the device becomes difficult to control.
Cleaning the TPR Material
Clean the device before and after use using mild soap and warm water, as recommended by the manufacturer.
Rinse thoroughly and allow it to dry completely before storage. Avoid harsh solvents, abrasive cleaners, and excessive heat.
TPR may be more difficult to sanitize thoroughly than non-porous materials such as silicone. Do not assume that washing or ordinary toy cleaners sterilize the product.
Storage & Inspection
Store the Annex in a cool, dry place away from direct sunlight and excessive heat.
Keep it separated from other toys and inspect the material before each use. Discontinue use if the TPR develops tears, cracks, tackiness, or other signs of deterioration.
Staff Tip
Check the unstretched opening measurements before choosing this style. The Annex has three separate openings, so comfort depends on the fit of both the main ring and the T-style separator. Start with a brief trial fit, keep removal easy, and never prioritize tightness over circulation and comfort.
