Oxballs Ergo Silicone Butt Plug is a smooth operator built for comfort—pure Liquid Platinum Silicone that’s blubbery and flesh-like, sliding in easy without a fuss. Its kidney bean curve and tapered neck lock it snug between your cheeks, while the flared base keeps it planted no matter how you move. Hand-poured in their USA factory, every plug’s a one-off—pick from five sizes, XS to XL, to stuff your hole your way. That soft, rubbery feel comes from their top-shelf mix, warm and stretchy enough to fit like it belongs. Go classic black, wild colors, or the extra-squishy Super Soft Smoke—whatever vibe you’re chasing. Phthalate-free and tough as nails, Ergo’s your go-to for a stretch that sticks.
