The Himeros Proteus in glans ring size. The design was pushed one step further. The central groove is now filled with exquisite deep blue crushed opal, which makes this ring sparkle in the sunshine. Do you dare to show it off?
 
The base material is almost indestructible tungsten carbide in natural silver colour with three CNC machined grooves. The ring glitters like a precious pearl.
 
Because of ergonomic design, all Himeros glans rings can be worn long term even under the foreskin.
