CONCAVE SPD 3.5" - Retention Style Silicone Nozzle

from $78.00

Designed for experienced users seeking both stretch and secure retention, this 9" (228.6 mm) long, concave-contoured model delivers firm pressure and deep fill in a balanced design. The 5.25" (133.4 mm) tapered tip provides smooth insertion before gradually increasing to a maximum diameter of 3.5" (88.9 mm) — delivering a satisfying and pronounced internal presence.

Just past the peak, the shape narrows into a 2.25" (57.2 mm) retention valley to help lock it in place during use. A wide 4.1" (104.1 mm) safety flange adds security and comfort, keeping everything stable. Insertable length is approximately 7" (177.8 mm), offering a deep but manageable experience.

You can customize the piece with your choice of color, silicone softness, and bore diameter. A no-bore (solid) version is also available for use as an enema retention plug or a dedicated stretching tool.

Photos will be updated soon. The shape follows the SPD Concave family design, scaled to a 3.5" diameter.
