Condom with detectable external raised sections - has raised sections at closed end and with regular geometrical structure, set in arrow shape with tips toward closed end

摘要

The condom has one or more detectable external raised sections (7,8) at the closed end (3), and they have a regular geometrical pattern. The height can decrease towards the open end (12). The raised sections can be arrow-shaped, with the tips (9) towards the closed end and incorporating transverse ribs (11). There can be two such raised sections on opposite sides. ADVANTAGE - Provides for reduced risk of erroneous fitting even in the dark.
