This metal butt plug from the Sinner Gear collection is heavier, larger and stronger than the standard butt plugs. The plug is made of smooth metal, which feels quite heavy. You can use the plug with any kind of lubricant and it is easy to insert thanks to the smooth shaft and pointy tip. You can easily remove the core, so the plug will not be as heavy. There is a pull ring at the end, so you can easily remove the toy after use.
