DO-NUT-2 Cockring Special Edition Black by Oxballs is a stretchy silicone cock ring designed for extended wear and enhanced sensation. Stretching up to five times its original size with outer circumference of 6.25 inches, it features premium PLUS+silicone blend construction and a sophisticated matte black finish. The 2-inch width and 0.5-inch depth provide optimal comfort for solo or partnered play seeking customizable pressure and extended performance.
The DO-NUT-2 works by wrapping around the base of the penis to restrict blood flow naturally, creating sustained firmness and heightened sensitivity during arousal. The elastic PLUS+silicone blend stretches to accommodate different sizes while maintaining consistent pressure without cutting off circulation. Its stackable design allows wearing it alone or layering multiple rings for intensified sensation and customized restriction levels.
Oxballs' proprietary PLUS+silicone construction combines elasticity with durability that standard rubber cannot match. The hypoallergenic material resists deterioration through repeated use while remaining non-porous for straightforward cleaning and storage. Those seeking rings that adapt to different body types and preferences can find our small cock rings collection at Adultsmart.

Pairing DO-NUT-2 with a vibrating stroker or partnered stimulation intensifies sensation by combining restriction with external stimulation. Stacking multiple rings from our stretchy cock rings collection creates layered pressure that some find more intense than single-ring wear. The stackable design allows experimentation with different pressure combinations to discover what intensity works best for your body and preferences.
After each use, rinse the ring under warm running water and gently clean with mild soap, paying attention to any crevices where moisture might accumulate. Pat dry completely with a soft cloth before storing in a cool, dark location away from direct sunlight or heat sources. Store it separately from other silicone products to prevent material degradation. The hypoallergenic PLUS+silicone blend is compatible with water-based lubricants but should not contact petroleum-based products, which can degrade the material over time.
DO-NUT-2 Cockring Special Edition Black uses hypoallergenic PLUS+silicone blend construction that resists allergic reactions and skin irritation. The non-porous surface prevents bacterial colonization and supports easy cleaning without harboring residue. Its material durability means years of reliable use without deterioration, while the engineered stretch capacity prevents tearing or permanent deformation through normal use.
This ring suits people seeking customizable pressure without rigid sizing constraints, as its five-times stretch capacity accommodates various anatomies comfortably. Those interested in enhanced firmness and extended performance will appreciate the restriction benefits without complicated application. The stackable design appeals to people exploring different sensation intensities, while the premium matte finish attracts those valuing aesthetic appeal alongside functional performance in their intimate collection.
For people frustrated by rigid metal or fixed-size rings that either pinch uncomfortably or slip off during use, discovering a material that stretches to fit while maintaining consistent pressure transforms what cock ring wear can feel like. The DO-NUT-2's extraordinary elasticity means no more choosing between proper fit and comfortable sensation—the ring adapts to your body rather than forcing your body to adapt to it. For those who have abandoned traditional rings because they created numbness or required constant adjustment, the engineered pressure distribution of the 2-inch width and 0.5-inch depth provides sustained firmness without circulation compromise. The stackable design shifts what customization means: instead of owning multiple rings in different sizes, one premium ring layers with others to create the exact sensation intensity you're seeking. For partners exploring enhancement together, the sophisticated matte black aesthetic makes it feel like a luxury accessory rather than a purely functional device, changing how comfortable someone feels incorporating it into intimate moments.
Our independent testers evaluated the DO-NUT-2's stretch capacity, pressure consistency, material durability, and comfort during extended wear across various body types. The ring stretched reliably to accommodate different sizes while maintaining shape integrity, with pressure remaining consistent throughout sessions without pinching or circulation restriction beyond intended sensation.
Testers reported that the matte finish provided excellent grip without slipping, and the material's warmth created a comfortable feel against skin. The stackable design functioned as described, allowing layered wear for intensified sensation. Individual results may vary based on anatomy, sensitivity, and usage patterns.
