PIGHOLE SQUEAL FF is our biggest pluggable, toyable hollow plug. This is a big toy for advanced butt-pluggers and FFisting pros. The veiny outside texture keeps this plug in place, the inner texture rings are for more pleasure.We hand pour these in small batches in Los Angeles—it's the only way to get the warm glossy liquid silicone finish—Platinum Cure silicone, it's the absolute best for feel and flexibility. Just the right stretch, keeps the hole open, it doesn't collapse, but flexible enough to fold for insertion.
