ERGO PLUG is a smooth silicone buttplug with a flared base and ergonomic kidney-shaped design.

The soft silicone flanges at the base keep ERGO PLUG securely snug between your sweaty cheeks for an all day stretch your piggy pucker won’t forget.

ERGO PLUG also comes in an array of colors to mix n’ match with your favorite gear or dungeon decor…or go old school with our more traditional black option, after all everyone looks good in black. 

Each unique ERGO PLUG is hand poured right here in our factory so no two plugs are alike. 

For an extra squishy alternative, try our super comfortable smoke option…it’s made from blubbery silicone that’s stretchy and soft to the touch.

Choose from 5 different sizes to best suit your hole stuffin’ needs. 

Lube safe: Water-based (recommended), silicone, hybrid, oil based.

Cleaning: detergent and hot water, diluted bleach/water solution, dishwasher.
