Kiotos COX - Strap-On Set with Monstar Dildo No. 31 - Black/Light Skin Tone

Taming a dragon is usually a complicated business. The Kiotos COX Strap-On Set with Monstar Dildo No. 31makes it a lot easier. This complete strap-on set combines the sturdy black COX Strap-On Deluxe harness with a striking silicone fantasy dildo that’s 21.5 cm long and 6 cm thick. No. 31 features a flesh-colored finish, pronounced texture, and a shape clearly inspired by the world of dragons.
Plus, you’re not just getting a harness that happens to fit a single dildo. The Kiotos COX comes with four interchangeable polished steel O-rings measuring 4, 4.5, 5, and 7 cm. For the substantial No. 31, you’ll use the largest 7-cm ring. If you want to switch things up later with another compatible strap-on dildo, the smaller sizes are already on hand.

COX Strap-On Deluxe: Sturdy Black Leather

The foundation of this set is the Kiotos COX Strap-On Deluxe harness. Kiotos crafts the harness from leather and opts for an open design with adjustable straps. This allows the fit to be customized to the body while keeping the dildo centered and securely in place.
The harness is suitable for a waist size up to approximately 100 cm. By adjusting the straps evenly, you can create a stable fit without tightening them unnecessarily. The black leather and polished metal O-ring give the COX a rugged, functional look that contrasts beautifully with the lighter color of No. 31.

Four O-rings make the harness versatile

A key advantage of the COX design is the interchangeable O-ring. This set includes four polished steel O-rings with inner diameters of: For the Monstar No. 31, the supplier recommends the 7 cm O-ring. The smaller rings allow you to insert other compatible dildos into the harness later on.

• 4 cm
• 4.5 cm
• 5 cm
• 7 cm

Always check more than just the shaft’s diameter. The base of a dildo must also be wide and sturdy enough to stay secured behind the chosen O-ring. This transforms the COX from a fixed set into a sort of wardrobe for strap-on dildos—only here, the accessories are a bit more adventurous than a new tie.

Monstar No. 31: Dragon-Inspired Fantasy Design

The Kiotos Monstar Dildo No. 31 stands out primarily for its imaginative design. Kiotos drew inspiration from a dragon for this model. Distinct textures and sculpted details run across the surface, giving the model a much more distinctive character than a conventional smooth dildo.
The flesh-colored finish creates an interesting contrast with the fantasy shape. As a result, No. 31 strikes a balance between the familiar and the otherworldly: the natural hue keeps the design somewhat understated, while the dragon-like relief conveys exactly the opposite message.
Due to the manufacturing process, the exact color may vary slightly from piece to piece. Minor differences in shade are therefore part of the product.

21.5 cm long and 6 cm in diameter

No. 31 has a total length of approximately 21.5 cm. Of that, about 15.5 cm is insertable. The diameter is approximately 6 cm.
This makes No. 31 clearly a substantial model. The relatively compact insertable length is combined with a generous thickness and a heavily textured surface. The result is a profile quite different from that of a long, slender strap-on dildo.
The 6 cm diameter makes this Monstar particularly appealing to users who are specifically looking for a larger size. Take your time, build up slowly, and use plenty of water-based lubricant. A dragon may come from the world of fantasy, but in the real world, 6 cm is still just 6 cm.

Body-safe silicone

Kiotos manufactures No. 31 from body-safe silicone. The material has a durable and low-maintenance surface and clearly highlights the various textured details of the design.
Preferably use a generous amount of water-based lubricant. It’s safe to use with silicone and helps reduce friction when using a dildo of this size.

Complete set, but not limited to a single dildo

Although No. 31 is specifically sold as a complete set with the COX harness, the two parts are not permanently attached to each other. You can remove the dildo from the harness and swap out the O-ring.
This makes the set appealing if you want to be able to use different sizes and shapes. The included rings ranging from 4 to 7 cm provide plenty of flexibility for this. No. 31 can take center stage today, while a smaller compatible dildo can easily take its place next time.

Use and Care

To use No. 31, insert the 7 cm O-ring into the COX harness and carefully attach the dildo. Then put on the harness and adjust the leather straps evenly. Before use, check that the base stays securely behind the O-ring and that the dildo is supported stably.
According to O-Products, the silicone dildo can be cleaned with warm water and mild soap. Allow it to dry completely afterward. You can wipe down the leather COX harness with a slightly damp cloth. Do not submerge the leather in water, and allow the harness to air dry completely before storing the set.
