Recommended for open bore options
This 3.75" (95.3 mm) maximum diameter model offers a bold step up in size while preserving the same carefully contoured retention shape that makes the SPD Concave series a favorite among advanced users.
At 9.5" (241.3 mm) total length with approximately 8" (203.2 mm) insertable, it begins with a smooth 5.5" (139.7 mm) tapered tip, transitioning into the full diameter for a wide, satisfying stretch. A 2.5" (63.5 mm) retention valley follows to help secure it in place, with a generous 4.5" (114.3 mm) safety flange at the base for added confidence during use.
Customize your plug by selecting your preferred color, silicone softness, and bore type. A solid (no-bore) option is also available for retention use or focused training.
While product photos are in progress, the form is based on the established SPD Concave shape, scaled to this larger size.
