Woof Hollow Plug w/ Stopper by Oxballs

Woof Hollow Plug w/ Stopper by Oxballs is a platinum-cure silicone butt plug with a hollow tunnel and removable plunger for dual sensations in one toy. Graduated sizing builds intensity from 14 cm to 19 cm circumference, and detailed veining grips with every movement. It suits experienced players who want texture, control, and adaptability.

What you're getting

Woof Hollow Plug w/ Stopper by Oxballs combines advanced design with practical functionality. The hollow silicone tunnel runs through the entire plug, and a removable plunger inserts from the base to seal it or withdraw to create an open passage. Unlike standard butt plugs that deliver sensation only through insertion and wear, this one shifts between two distinct experiences: filled (plunger in) for traditional plug sensation, or hollow (plunger out) for unique internal sensations and creative partnered play.

The plug's graduated circumference starts at 14 cm and expands to 19 cm, so each centimetre of depth brings increasing stretch and intensity. Platinum-cure silicone grips firmly without sticking, and the textured veining stimulates the anal walls as you move or adjust position. A wide, flared base with integrated stopper prevents over-insertion and anchors the plug securely during extended wear.

Main features

• Hollow tunnel: Runs the full length of the plug, allowing the removable plunger to seal or open the passage for two completely different play modes.
• Removable plunger: Swap between filled and hollow sensations mid-session without stopping; the plunger seats snugly and lifts cleanly away.
• Graduated sizing: Circumference increases from 14 cm to 19 cm as you go deeper, building sensation progressively rather than delivering one fixed stretch.
• Detailed veining: Textured surface grips and stimulates the internal walls with every slight movement, intensifying sensation during insertion and sustained wear.
• Integrated stopper: Wide base with built-in safety ridge prevents over-insertion and holds the plug securely in place during extended sessions.

The technical detail

• Total length: 16.5 cm; usable insertion depth 14.5 cm from rim to stopper ridge.
• Circumference range: Graduated from 14 cm at the tip to 19 cm at the widest point before the base.
• Material: Platinum-cure silicone, hypoallergenic, non-porous, and body-safe for internal use.
• Weight: Substantial enough to be felt during wear; sinks into position naturally without shifting.
• Colour: Solid black silicone throughout; veining is integral to the moulded structure, not applied.
• Plunger: Silicone rod that fits flush into the hollow tunnel; removable, not permanently attached.
• Box contents: Woof Hollow Plug w/ Stopper, removable plunger, storage pouch, and care card.

Using a hollow butt plug without rushing

Start with warm-up: the hollow design means you're training internal tissue as well as the entrance, so begin with relaxation and slow breathing before insertion. Apply lubricant generously to both the plug and your body; silicone-based lube glides smoothly on platinum silicone and stays slick longer than water-based. Insert the plug tip-first at a 45-degree angle, pausing as the circumference increases every centimetre—this graduated stretch builds intensity gradually and lets your body adjust. Once fully seated, the stopper anchors it safely.

The removable plunger doubles your options: wear the plug filled first to experience traditional sensation and fullness, then withdraw the plunger to shift the experience entirely. That hollow centre creates new sensations during movement or partnered play. If you explore Beginner Prostate Beads alongside this plug, the progression from beads to graduated stretching tools mirrors natural training. Never force depth; if you reach a circumference that feels too intense, pause, breathe, and let your body relax rather than pushing deeper. Withdraw slowly using the same angled approach on removal.

Who should buy it

Care and storage

Wash the plug and removable plunger separately with warm water and mild soap, or use a dedicated toy cleaner; silicone is non-porous and dries completely within minutes. Store both pieces in the included pouch in a cool, dry place away from extreme heat or sunlight, which can degrade silicone over time. Do not store sealed or damp. Keep away from silicone-based lubricant if you intend to use water-based lube alongside other toys, as mixing can cause surface softness. Check the stopper ridge periodically for any splits or wear.

More on the subject

Hollow plugs create sensations that solid plugs cannot match: the interior passage adds a layer of stimulation and opens possibilities for partnered play that standard designs do not allow. Understanding how graduated sizing works helps you progress safely and recognise when your body is ready to move deeper.

What to expect

The hollow tunnel feels distinct from solid plugs the moment it enters; you'll sense the shape and structure in a way that a simple tapered design does not create. The graduated circumference means that the first few centimetres feel manageable, but each subsequent centimetre adds noticeable stretch—this is deliberate and requires you to pace yourself rather than expecting quick insertion. Many people reach the middle circumference and pause to breathe or adjust position before going deeper; that pause is normal and healthy.

Switching the plunger mid-session creates a genuine shift in sensation, not a minor tweak. With the plunger in, the plug feels full and anchored; withdrawing it transforms the toy into something that emphasises internal passage and hollow space. First-timers often underestimate how much the plunger matters and are surprised by the difference when they try both modes.

The textured veining grips visibly more than smooth silicone does, which amplifies sensation during movement and wear. If you're accustomed to smooth plugs, the added texture can feel intense at first; this settles once your body adjusts to the feedback. The substantial weight stays with you during wear and prevents the light, nearly-weightless sensation of smaller toys.

Cleaning is straightforward because silicone is non-porous, but the plunger's fit means you need to wash both separately and dry both fully before storage. The plunger doesn't stain or hold odour, and its snug fit ensures it won't rattle or shift during use.
