Tantus Severin Medium Silicone Butt Plug

Best For:

• Intermediate anal play
• Extended wear comfort
• Harness-compatible pegging
• Body-safe silicone preference
• Easy sterilization between partners

The Tantus Severin Medium is a graduated silicone butt plug designed for wearers who've moved past beginner sizes and want something that stays put. Its tapered tip and dual staging bulbs let you ease into the 2-inch widest diameter at your own pace, while the long neck and butterfly base anchor it comfortably between the cheeks during extended sessions or active play.

At 4.6 inches insertable, the Severin Medium offers satisfying fullness without excessive length — ideal for couples exploring strap-on play (the flared base is harness-compatible) or solo wearers who want stability during movement. The matte silicone texture grips just enough to stay secure with water-based lube, and the flexible stem adapts to your body's contours without digging in.

What sets Tantus apart is their proprietary silicone formula — denser than most plugs in this price range, which translates to more substantial pressure and better long-term shape retention. Unlike porous materials, you can sterilize this plug by boiling or bleaching it, making it safer for fluid-bonded partners or anyone with latex allergies who can't rely on condom barriers.

Key Features

• 2-inch maximum diameter with tapered entry and dual bulbs
• 4.6-inch total length with long retention neck
• Butterfly base for extended wear and harness compatibility
• 100% platinum-cured silicone (hypoallergenic, non-porous)
• Boilable and dishwasher-safe for complete sterilization
• Matte finish for controlled slip with water-based lube
• Flexible enough to move with your body, firm enough to provide pressure

How to Use

Apply generous water-based lube to the plug and your body. Insert the tapered tip first, pausing at each bulb to let your muscles relax before continuing. The long neck will sit inside your body with the butterfly base resting externally — this design prevents over-insertion and makes removal easy by gripping the base. For harness use, thread the base through the O-ring before securing straps. After use, wash with warm soapy water or boil for 3 minutes to sterilize.

Compatibility

• Lubricant: Water-based only — silicone lube degrades silicone toys over time
• Harness O-rings: Fits standard 1.5–2-inch rings; butterfly base sits flush against pelvis
• Condom barriers: Compatible with latex, polyurethane, and nitrile if sharing between partners
