Jack is interesting precisely because it does not try to imitate a large solid plug. Its 3.5 cm tunnel leaves the centre open while the silicone rim maintains the opening. The sensation therefore combines stretching with hollowness. With an outer diameter of 7.1 cm, it remains an expert model that requires preparation, time and plenty of lube.
Jack is not a standard plug: its fully hollow centre maintains a genuine 3.5 cm open channel once the toy is in place.
The concept that changes everything: a tunnel, not a solid core
The opening runs through the plug from end to end. Its body therefore surrounds the entrance instead of filling the centre, creating a very distinctive held-open sensation and a visual effect that a solid plug cannot offer.
Short, but genuinely XL in width
Jack stands only 8.7 cm high but reaches 7.1 cm externally. Progressing to this size demands serious preparation: its compact format should not be confused with a small plug. The internal opening measures 3.5 cm.
Soft silicone to assist insertion
The body can be compressed and folded slightly between your fingers, helping you guide the rim. Once released, it returns to shape and maintains the tunnel effect. The flared base stays outside and makes anal use safer.
For experienced players
Jack is for anyone already comfortable with large diameters who wants a sensation beyond simple fullness. Prepare with several sizes, use plenty of lube and give each stage time to become comfortable.
Directions and care
Lubricate the entire surface with water-based lube, including the inner edge, then compress and insert slowly without forcing. Do not introduce any accessory into the tunnel without checking its compatibility and safety. After use, wash the inside of the channel thoroughly, rinse and leave it open to dry.
