What Is a Hollow Butt Plug?

A hollow butt plug is a tapered plug with a flared base and an open channel from tip to base, so instead of filling the body it keeps it open. Most are soft silicone with a wide, smooth bore; a few are clear plastic so you can see through, and the top of the range is steel with a mechanical spread.

They come from the same place as anal training kits and huge toys: blokes who want to go further and stay comfortable there. Our hollow butt plug range runs to about 13 plugs from a $39 clear tunnel to a $465 Oxballs statement piece.

Are Hollow Butt Plugs Right for You?

If you already wear solid plugs comfortably and want the next thing, a hollow plug is it: the open feeling is unlike anything solid, and it lets a partner, a lube shooter or a smaller toy in while it is worn. It is also the tool for building comfort with size in a controlled way.

It suits experienced plug wearers, blokes working towards fisting or huge toys, couples who want access during play, and anyone curious about the open sensation. If you are new to plugs entirely, our butt plug guide and anal training kit guide come first.

The honest trade-off is that a hollow plug is harder to insert than a solid one of the same size, because the tunnel means it cannot compress, and it needs more lube and more warm-up. It is not a beginner's first plug, and steel versions are heavy and unforgiving.

Types of Hollow Butt Plugs: Which One Suits You?

Hollow butt plugs come in four types, and material plus diameter decide who they suit: silicone tunnel plugs, clear view plugs, XL and specialist silicone, and steel spreaders.

Silicone tunnel plugs

Soft, flexible and the easiest hollow plugs to insert. Perfect Fit's Tunnel Plug in Medium, Large and XL is the range most blokes work through, one size at a time.

Clear view plugs

Rigid, transparent, and made to see through. Master Series' Medium View Hollow Butt Plug and Large View Hollow Butt Plug are the two sizes; the Butt Craze Clear 15 cm Hollow Butt Plug from Excellent Power is the budget version.

XL and specialist silicone

Bigger bores for experienced players. Brutus' Gobbler Silicone Hollow Butt Plug has a wide tunnel and a soft body; the XXL Ergo Bum Hollow Butt Plug is their XXL ergonomic plug; the 5.5" Woof Hollow Butt Plug is Oxballs' premium heavyweight.

Steel spreaders

Stainless steel with a mechanical spread you open once it is in. The Forced Spread Steel Anal Explorer is the one we stock; heavy, cold and strictly for experienced players.

How to Choose Your First Hollow Butt Plug

Choose in this order: diameter, then material, then bore width, then extras. Diameter is the one that decides whether you enjoy it or put it in the drawer.

1. Diameter: one size under what you take solid

A hollow plug does not compress, so start a size below your comfortable solid plug. For most experienced wearers that is the Medium Tunnel Plug; the Large Tunnel Plug is the step up.

2. Material: silicone first, rigid later

Silicone flexes on the way in and warms quickly. Clear plastic and steel are rigid, which is what makes them see-through or spreadable, and also what makes them harder work. Start soft.

3. Bore: how wide does the tunnel need to be

A narrow tunnel keeps you open; a wide bore like the Gobbler Silicone Hollow Butt Plug lets fingers and toys through. Decide what the plug is for before you decide how big the hole is.

4. Extras: view, spread or statement

The Medium View Hollow Butt Plug lets you see inside, the Forced Spread Steel Anal Explorer spreads on command, and the 5.5" Woof Hollow Butt Plug is the plug for blokes who want the biggest, best-made one there is.

Materials & Body-Safety

The silicone plugs here are body-safe platinum-cure silicone: non-porous, easy to clean and soft enough to flex on insertion. Use water-based lube only; silicone lube degrades them. Clear view plugs are rigid, non-porous body-safe plastic that takes any lube and cleans with soap and water.

Steel spreaders are stainless: non-porous, heavy, and they hold temperature, so warm them before use. Every plug here has a proper flared base. Nothing without one belongs anywhere near this category.

How to Use a Hollow Butt Plug

Warm up with a solid plug or fingers first; a hollow plug goes in after the body is relaxed, not instead of the warm-up. Lube generously, inside and out, using a lube shooter for the inside, and insert slowly with steady pressure until the base sits flush.

Once it is in, the open feeling arrives on its own. Use the tunnel for what you bought it for: more lube, a partner, a smaller toy, or just the sensation. Wear time for a first session is fifteen to thirty minutes.

A steel spreader is inserted closed and opened gradually once seated. Stop at sharp pain every time, hollow or solid.

Care, Cleaning & Storage

Wash the plug inside and out with warm water and a toy cleaner straight after use; the tunnel is where residue hides, so run water through it and use a soft brush if needed. Silicone and steel can be boiled.

Dry fully and store in a pouch away from other silicone toys. Check the base and the tunnel edges for tears before every use and retire a plug that shows any.
