Knot Dildos

A knot is a spherical expansion set low on the shaft, distinctly wider than the shaft above it. Once it passes, the sphincter closes behind the narrower collar and holds the shaft in place — physical retention, not muscular effort — and removal takes the same deliberate pressure as entry. That makes knot diameter the number that matters most, so Korym publishes it for every size of every knotted model. Knots appear on canine, equine and hybrid profiles here, in single and dual density platinum-cured silicone. Generous water-based lubricant is required in both directions; none of these are beginner sizes.
