Some plugs just don’t stay where you want them—the Drain-O Flow-Thru Plug was built to solve exactly that problem, delivering a secure, all-day fit through genuine engineering rather than guesswork.

Material & Construction

Handcrafted in Los Angeles by Oxballs, the Drain-O is made from custom-mixed Liquid Platinum Silicone—a body-safe, non-porous material that’s blended by hand for every batch to hit the precise firmness and flexibility each design demands. The result is a toy that feels intentional, not mass-produced. The innovative shape features a double-seal design: a flared cone tip and a fat second lip halfway to the base, with a gap between the two that lets your body conform naturally for a confident grip. Subtle textured indentations around the midsection channel lube and air front to back, keep the plug centered, and reduce unwanted twisting. The defining feature is the pencil-thick airhole that runs straight through the center, venting pressure behind the plug so your body doesn’t feel the urge to expel it—a small detail that makes a meaningful difference in long-wear comfort.

How to Use

Apply a generous amount of water-based lubricant to both the plug and yourself before insertion. Insert slowly, allowing the double-seal shape to seat at a comfortable depth. The flow-thru vent will help equalize pressure as you relax into the fit. The textured channels help retain lube and keep the plug positioned even during extended wear. Start with shorter sessions if you’re new to larger plugs and work up to longer wear as comfort allows.

Care & Cleaning

Because this plug is made from 100% silicone and has no motor or electronics, it can be thoroughly cleaned after every use. Wash with warm water and a dedicated toy cleaner, or boil for up to three minutes for a deeper sanitize. Pay extra attention to the center vent channel—a thin brush or steady stream of water works well to flush it through. Allow to air-dry completely before storing in a clean pouch or container away from other silicone items.
