Kum keeper hollow but plug

Ready to plug, pour, and preserve?
The Kum Keeper is your go-to tool for advanced fill play and liquid fantasy fun. Made from premium, flexible silicone, the outer plug features a tapered head for smooth, easy entry—and a shape that makes you feel deliciously full.

Remove the inner stopper to inject lube, cream, or more using your favorite funnel, tube, or nozzle. When you’re nice and loaded, pop the stopper back in to keep every last drop exactly where it belongs.

No leaks. No mess. Just maximum capacity kink.
