The Ryder Plug from Tantus is a four and a half inch long silicone anal plug featuring a gradual curve from the body to the neck of the plug and a flexible base designed with comfort in mind.
Here is a small snippet from Karen Blue’s review of the Ryder Silicone Plug:
I felt like I could wear it all day. There are no seams on the insertion portion at all. The only marking on this plug is a small etching on the side of the base that says Tantus. The silicone is shiny and smooth. The Ryder is firm with a slight squishy feeling. The material is a bit tacky so you will want to store this away from dust and lint.
