Tantus Severin Large Anal Plug Onyx

Meet Severin — the progressive anal training plug that grows with your pace. Available in three sizes, Severin is crafted to guide you from first gentle entry to more immersive fullness, all in a single, ergonomic design. The Large Onyx edition is the perfect next step for those who’ve mastered beginner play and are ready to explore deeper sensations with confidence.

Two-tiered design for controlled progression

The Severin’s signature two-tier profile starts with a small nose for easy entry and travels into a longer, stimulating neck. This deliberate slope minimizes sudden muscle "shocks" while sliding in, helping you relax and enjoy the sensation as you train. Two staging areas give you tangible milestones, use the smaller stage to warm up, then ease into the larger portion as you expand tolerance and desire.

Unmatched safety meets intense satisfaction

With a wide rectangular base that sits outside your body, Severin provides secure grounding and effortless retrieval, so you can focus on the experience without worry. The long neck is designed to grip gently as you progress, delivering fuller, deeper pressure that enhances pelvic floor engagement and internal stimulation. This is anal play that respects your body’s natural limits while encouraging steady growth.

Premium silicone that’s safe, hygienic, and easy to care for

Made from Tantus’ ultra-premium silicone, the Severin is a non-porous, hypoallergenic material that’s safe for the most intimate use. It’s boilable for sterilization, bleach-cleanable, and dishwasher safe, giving you flexible cleaning options. The soft silicone feels natural and cushions as it compresses with a subtle spring back, delivering a comfortable, filling sensation you’ll want to revisit again and again.

Who this is for and how to use it

This plug is ideal for anyone who wants a structured path from entry to deeper penetration, all while maintaining control and comfort. Begin with proper lubrication, relax your breathing, and insert slowly. Use the smaller stage as a warm-up, then gradually work into the larger stage as your body accommodates. The Onyx Large is particularly well-suited for those who appreciate a longer neck for deeper stimulation and a sturdy base for safety during extended wear.

Why choose the Severin Large Over other options

Unlike simpler, single-density plugs, Severin offers a thoughtful progression inside a single shape, reducing the need to swap toys mid-session. The two-stage experience paired with a long neck means you can steadily increase fullness, harness pelvic floor engagement, and enjoy sustained comfort. Coupled with Tantus’ trusted silicone health and cleaning advantages, this plug stands out for repeatable, safe, and satisfying training.

Care and storage tips

After use, wash with warm water and mild soap or your preferred toy cleaner. If sterilizing, boil for a few minutes and let it air dry. Store separately from porous materials to preserve the silicone’s integrity and keep it free from lint and dust.
