Gunnar Realistic Silicone 8-Inch Penis Extender | Raeven CORE

The Gunnar Realistic Silicone Penis Extender from Raeven CORE is an 8-inch sleeve designed to add temporary length and girth during partnered use.

Made from silicone, Gunnar has a realistic sleeve format with a flexible inner opening and an integrated ball loop to help keep it positioned at the base. The sleeve is listed as adding 1.5 inches of length and up to 20% more girth while worn.

The inner sleeve opening measures 1.5 inches in diameter, giving you a clear fit measurement to compare before use. A separate 1-inch inner-diameter ball loop sits at the base to provide additional retention during movement.

Gunnar is fully manual, so there are no batteries, charging cables, vibration settings or powered controls to manage. The focus is on added temporary size, realistic styling and a straightforward wearable fit.

For a clear TPE extender that adds more listed length, compare the Elys 3-Inch Clear Penis Extender Sleeve, which is designed to add up to 3 inches of length while worn.

For a sleeve focused more heavily on texture than extension, compare the Rybbe Textured Penis Sleeve with Ball Loop, which uses an externally ribbed design and a nodule-lined interior.

For a separate silicone cock-ring option, explore the Vigor Silicone Vibrating Cock and Ball Ring.

Specifications

Fit, Lubrication and Care

Apply Slide Water-Based Lube 100ml to the penis and inside the sleeve before fitting Gunnar. Add more water-based lubricant to the outside before partnered use.

Guide the penis into the sleeve slowly and position the ball loop carefully around the base. The sleeve and loop should feel secure without painful tightness, pulling, pinching, numbness, coldness or difficulty removing them.

Because Gunnar adds both length and girth, begin partnered use slowly and make sure the added size remains comfortable for both people.

Clean the silicone sleeve after use with Raeven Cleanse Essential Toy Cleaner 250ml, which lists silicone among its compatible materials. Pay attention to the inside of the sleeve and around the ball loop, then allow the product to dry fully before storage.
