Made in Greece, handmade, from plastic leather and materials, excellent quality and durability. It has 4 metal rings (1 + 3). The first, 5.5cm in diameter, is the most effective because it grips and tightens testicles and penis, so as to give a more effective erection and longer duration of your foreplay. The next 3, 3.5cm in diameter, hug the penis and ensure more confidence and strength.
