The OXBALLS PIG-HOLE DEEP I in black is a hollow butt plug: a thick, open tube of platinum silicone that holds you open while it's worn, rather than simply filling you. It's the longer, more tapered follow-up to the original PIG-HOLE, and DEEP I is the smaller of its two sizes, roughly the size of a medium plug. The open core is the point, letting a partner, a toy or lube pass straight through while it stays in place.

How a hollow butt plug feels

A solid plug gives pressure and fullness. A hollow plug adds the sensation of being spread open around a ring, with the inside left clear. OXBALLS uses its thick, fleshy Pure Platinum Silicone, which is firm enough to hold the opening wide but soft enough to flex as you move, and it warms quickly to body temperature. Inside, the chamber is lined with textured ridges that give the penetrating partner extra sensation as they slide through.

Shape and how it stays put

From the tip, the plug tapers gradually out to a thick knot, then narrows at a long neck before reaching a flared base. The knot is the widest point at 7.5 in around; once it passes the sphincter, the narrower neck lets the muscle close around it and the base stops it travelling further in. That combination keeps it seated during movement, including when a partner is thrusting through it. The narrowest usable circumference is 5.25 in, and the inside opening is 1.5 in across.

Is DEEP I the right size?

This anal toy is not a first plug. A 7.5 in circumference at the knot is around 2.4 in across, so it suits people who are already comfortable with medium plugs or a partner of average girth. If that's a stretch for you now, work up with a graduated plug set first. The larger PIG-HOLE DEEP II is aimed at very experienced players. OXBALLS also makes the shorter, rounder Pig Hole Morph if you'd like a different shape.

Using it

  • Warm up thoroughly with fingers or a smaller toy.
  • Use a generous amount of water-based, hybrid or oil-based lube; OXBALLS doesn't recommend silicone lube on this silicone.
  • Insert slowly with steady pressure, breathing out as the knot passes. Never force it.
  • Add more lube through the open centre as needed.
  • Remove it gently, easing the knot back out the same way it went in.

If you'll use it for penetration through the core, the penetrating partner should use plenty of lube too, and condoms are recommended if you're not fluid-bonded.

Cleaning

Wash it in warm soapy water after each use, using a bottle brush to clean the inside of the tube. OXBALLS lists it as dishwasher safe. Store it in a breathable cloth pouch or a clean cotton sock, away from other toys. Black silicone hides staining, but check the inner ridges for leftover lube before putting it away.

Frequently Asked Questions

Helpful answers about OxBalls PigHole Deep I Hollow Plug - Black Small.

What is a hollow butt plug for?

It holds the anus open around an open core. People use it for the stretched, gaping sensation, for penetration through the plug while it stays in, or to add lube or other play through the centre. It's an advanced toy rather than a beginner one.

Is the PIG-HOLE DEEP I suitable for beginners?

No. The knot measures 7.5 in around, roughly 2.4 in across. It suits people already comfortable with medium plugs. If you're new to anal play, start smaller and work up gradually.

Which lube works with this hollow plug?

OXBALLS lists water-based, hybrid and oil-based lube as safe, and doesn't recommend silicone lube for its platinum silicone. Thicker water-based gels or hybrids tend to last longer during stretching play.

How do I clean the inside of the plug?

Use warm soapy water and a narrow bottle brush to scrub the textured inner chamber, then rinse well. OXBALLS says it is dishwasher safe, which is handy for a thorough clean. Let it dry fully before storing.

What's the difference between DEEP I and DEEP II?

DEEP I is the smaller size, roughly a medium plug with a 7.5 in maximum circumference. DEEP II is larger and aimed at very experienced players who already enjoy fisting-level stretching.

Can a partner use a condom through it?

Yes, and it's a good idea unless you're fluid-bonded. The 1.5 in inner opening has textured ridges, so lube both the condom and the inside of the plug generously for smooth movement.

How long can I wear this anal toy?

Build up gradually, starting with short sessions. Remove it if you feel pain, numbness or a burning sensation. Stretching should feel intense but never sharp, so let comfort guide how long you keep it in.
