The Mark O2 is the goldilocks of representational toys: not too big, not too small! Plus, it’s harness-compatible and made of ultra-premium, dual-density silicone.

Mark O2 has a firm core and super-soft outer layer of pure silicone, keeping the dildo firm enough for extended play and also holding heat, making it simulate body temperature.

This realistic, also called anatomically correct, toy features a slight curve, subtle veins, and a slightly oversized head. It is nonporous, boy-safe, and built to last a lifetime!

Mark O2 is a realistic/anatomical dildo with just the right amount of detail. Available in two skin tones, this representational toy is designed to please.

The thick base allows for added stability when used with a harness, while the subtly textured veins on the shaft offer extra pleasure. Its shaft has a slight curve for added satisfaction, and features a slightly exaggerated head with a firm inner core. The smooth material holds heat and warms the entire dildo, simulating a skin-like feel akin to natural body temperature.
