Ultracore Core Ballstretcher with Axis Ring in Red Ice

The Ultimate Dual-Component Ball Stretching System

The Ultracore Core Ballstretcher with Axis Ring in Red Ice represents a revolutionary approach to ball stretching with its innovative two-piece system. This isn't just a single stretcher—it's a complete kit designed to deliver progressive, customizable stretch with superior comfort. The striking Red Ice colorway combines deep red tones with translucent clarity, creating a visually stunning appearance that looks as premium as it feels.

Engineered for Progressive Stretch

The CORE Ballstretcher

The foundation of this system is the CORE stretcher itself, featuring a sophisticated multi-layer design. The exterior showcases pronounced ribs that provide texture and grip, while the interior is engineered with a smooth hourglass tunnel that wraps around your sack with a medium-firm squeeze. This dual-texture approach means the outer surface grips and stays in place while the inner surface maintains comfortable contact with your skin throughout wear.

The padded middle section is key to all-day wearability—it cushions and distributes pressure evenly around your scrotum, preventing the discomfort and pinching that can occur with simpler designs. The thoughtful thickness provides substantial stretch without sacrificing comfort.

The AXIS Power Ring

The included AXIS ring is what elevates this from a standard stretcher to a complete system. Featuring channel ribs on its interior surface, the AXIS is designed to stack perfectly with the CORE stretcher—its ribs interlock with the CORE's outer ribs for a secure, unified fit that won't separate during wear. This gripping connection means you can add weight and length to your stretch simply by stacking the AXIS ring below the CORE.

The AXIS also functions brilliantly as a standalone cock ring or ball ring, making this truly a versatile two-in-one purchase.

Premium Plus+SILICONE™ Material

Crafted from Oxballs' proprietary extra-soft Plus+SILICONE blend, the Ultracore system delivers a velvety, rubbery texture that's incredibly smooth against skin while maintaining the firm structure needed for effective stretching. This isn't standard silicone—the Plus+ formulation offers enhanced flexibility and softness without compromising the material's ability to maintain its shape and provide consistent pressure.

The medium-firm squeeze feels secure without being restrictive, and the material warms to body temperature quickly for a natural feel. Both pieces are 100% body-safe, non-porous, phthalate-free, and built to last through countless sessions.

Lube-Friendly and Easy to Use

Both the CORE stretcher and AXIS ring are compatible with water-based and silicone-based lubricants, making application smooth and comfortable. For first-time users, apply a generous amount of lube to both your body and the interior of the stretcher, then gently work one testicle through at a time. The flexible material stretches to accommodate you, then settles into place with its secure grip.

The hourglass interior tunnel naturally guides your anatomy into the optimal position, while the outer ribs prevent any unwanted slippage during movement or play.

Customizable Wearing Options

• CORE alone: Perfect for beginners or moderate stretch sessions
• AXIS alone: Functions as a cock ring or light ball ring
• CORE + AXIS stacked: Maximum stretch and weight for advanced users
• Multiple AXIS rings: Stack additional rings for extreme stretching (additional rings sold separately)

Care and Maintenance

Clean both pieces thoroughly after each use with warm water and mild soap or dedicated toy cleaner. The non-porous silicone won't harbor bacteria, and the material is durable enough for regular use. Allow to air dry completely before storage. Keep away from direct sunlight and extreme temperatures to maintain the material's integrity and vibrant Red Ice color.
