CONCAVE SPD 4" - Retention Style Silicone Nozzle

from $98.00

For those who demand the absolute maximum in stretch and fullness, this 4.0" (101.6 mm) diameter version of the SPD Concave plug is the largest currently available in the series. With a total length of 10" (254 mm) and an insertable depth of 9" (228.6 mm), it's designed for highly advanced users who want both depth and girth in one tool.

The 5.75" (146.1 mm) tapered tip allows for gradual, controlled entry before reaching the 4.0" swell, which sits about midway down the shaft. A 2.55" (64.8 mm) retention valley helps keep it securely in place during extended use, and the 4.7" (119.4 mm) safety flange ensures stability and comfort.

Available with your choice of bore (open or solid), color, and silicone firmness. This plug is ideal for retention scenarios or advanced stretching sessions.

Photos will be uploaded soon. The design is based on the proven SPD Concave contour, proportionally scaled for this extreme size.
