There is a reason it is our most popular buttplug—it feels amazing! Hand poured in small batches using liquid platinum cure silicone. Oxballs loves color, so we’ve added NEW platinum color to ERGO—it’s a swirl of metallic platinum and black—kinda fancy for a toy you put in your butthole, but it is sexy AF and so much cooler than boring solid black! Each one is unique with cool color swirls .
