SEI MIO Perfectly Pegged Adjustable Strap-On Harness with 6.5 Inch Silicone Dildo Strap-On Set

Complete Strap-On System for Confident Play

This complete harness kit delivers everything needed for effective pegging or partner play in one package. The system pairs a comfortable, adjustable harness with a 6.5-inch slimline silicone dildo engineered specifically for anal play, plus three interchangeable O-rings for future compatibility with other attachments.

Slimline Silicone Dildo Built for Comfortable Entry

The included dildo measures 6.5 inches in total length with an insertable length designed for gradual, comfortable penetration. Crafted from body-safe silicone, the shaft features a smooth, velvet texture that glides easily with water-based lubricant. The slimline profile reduces initial resistance while the gently tapered head assists with entry. A pronounced flared base locks securely into the harness O-ring and prevents over-insertion during use.

The flexible-yet-firm construction allows the dildo to conform slightly to the body's natural contours while maintaining enough rigidity for effective penetration. This balance makes the attachment suitable for first-time users while remaining satisfying for those with more experience.

Adjustable Harness That Stays in Position

The harness uses a sturdy nylon construction with fully adjustable straps that accommodate hip sizes from approximately 30 to 52 inches. Four adjustment points—two at the waist and two at the legs—allow precise fitting to hold the dildo at the correct angle without shifting during movement. The straps distribute pressure evenly across the hips rather than creating uncomfortable pressure points.

A small integrated pocket positioned at the front of the harness accommodates most standard bullet vibrators, adding clitoral or vulvar stimulation for the wearer during use. The pocket keeps the vibrator positioned correctly without requiring additional adjustments.

Three O-Rings for Versatile Compatibility

Three silicone O-rings in graduated sizes accompany the harness: 1.5 inches, 1.75 inches, and 2 inches in diameter. These rings stretch to accommodate dildos with base diameters slightly larger than the ring itself, providing secure retention across a wide range of toy sizes. The silicone material grips the dildo base without damage while remaining easy to remove when switching attachments.

The O-ring system sits in a reinforced fabric backing that prevents the ring from pulling through during vigorous use. Simply stretch the desired O-ring over the dildo base before inserting it through the harness opening.

Durable Materials Built to Last

Both the dildo and O-rings use premium silicone that resists tearing and maintains its structure through repeated use and cleaning. The harness fabric withstands regular washing without fraying or losing elasticity in the adjustment straps. Metal hardware at connection points provides reliable fastening that won't bend or break.

Care and Compatibility

Clean the silicone dildo and O-rings with warm water and mild soap or specialized toy cleaner after each use. The silicone components can be boiled for 3-5 minutes for thorough sterilization. Machine wash the harness on a gentle cycle or hand wash with mild detergent, then air dry completely.

Use only water-based lubricants with the silicone components. Silicone-based lubricants will degrade the dildo and O-rings over time.
