## Emma's take

Soft on the surface, firm underneath, curved right where it counts.

Mark's dual-density build pairs a soft outer layer with a firmer inner core, so pressure holds its shape while the surface still gives. The slight curve and exaggerated head are shaped for come-here pressure against the front wall, and the thicker base is built for harness play. Reviewers know Tantus for a realistic feel most silicone dongs don't manage. Newer to dual-density silicone or working with 1.6 inches of girth, start slow and lube generously. Anyone wanting something slimmer or straighter should look elsewhere in the lineup.

## Frequently asked questions

## What makes the Tantus Mark O2 dildo feel different from standard silicone dongs?

Mark uses Tantus's dual-density O2 silicone: a soft outer layer over a firmer inner core, so it gives at the surface while holding its shape underneath. The blend is designed to read closer to real than single-density silicone.

## Is the Tantus Mark dildo harness compatible?

Yes. It's built with a thicker base specifically for stability in a harness, on top of working fine for hand-held or standing solo play.

## How do I clean and sanitize the Mark O2 dildo?

Wash it with warm water and mild soap after every use, or go further: it's boilable, bleachable, and dishwasher safe since it's 100% silicone.

## What lube works with this dildo?

Stick to water-based lube. Silicone-based lube breaks down silicone toys over time, so save the silicone formulas for latex or glass.

## What size is the Tantus Mark O2 dildo?

It measures 6.25 inches in total length with a maximum shaft diameter of 1.6 inches and a 1.4-inch head, an average size built for a realistic, familiar feel.
