OxBalls Drain O Flow Thru Buttplug Black

Staying put is the whole point – and the OxBalls DRAIN O is engineered around exactly that. A double lip seal, a flow-through air vent, and anti-twist divots work together to keep this plug right where you want it, no matter how hard your body tries to push back.

The conehead shape features two distinct flares: one at the tip and a fat, rubbery second lip halfway to the base. The gap between them gives your body more surface area to grip, creating a secure double seal that locks the plug in place. The subtle indentations running around the middle channel lube and air from front to back, keeping the plug centred and cutting down on unwanted rotation.

That pencil-thick, 7mm air flow hole through the centre is more than a design quirk. Pressure build-up behind a plug is one of the main reasons your muscles want to expel it – the vent equalises pressure inside and out, so the plug stays put with far less effort on your part.

Handmade from Liquid Platinum Silicone

Every DRAIN O is handcrafted using OxBalls’ Liquid Platinum Silicone, custom mixed by hand for each batch. That hands-on process is what gives the silicone its distinctive feel – something machine-made production simply can’t replicate. Because it’s hand-poured, slight size variations can occur, but the specs are: total height 121 mm, widest circumference 181 mm, and a weight of 0.27 kg.

FAQ

What is the DRAIN O made from?

The DRAIN O is handcrafted from Liquid Platinum Silicone, custom mixed by hand for every batch OxBalls produces.

What are the dimensions?

Total height is 121 mm, widest circumference is 181 mm, the air flow hole is 7 mm in diameter, and the plug weighs 0.27 kg. Because these toys are hand-poured, slight size variations can occur.

How does the flow-through vent work?

A pencil-thick 7 mm hole runs through the centre of the plug. It equalises pressure inside and out, reducing the natural tendency of your muscles to expel the plug – helping it stay in place longer and more comfortably.

Orders are sent in discreet packaging with no indication of contents, and we ship across Australia.
