The stronger TENGA Hard Boiled Eggs feature a firmer elastomer sleeve, producing greater feelings of tightness while every ridge or swirl is exemplified from the original Egg. Each egg has a hard outer shell, which twists open to reveal a snug egg-shaped elastomer masturbation sleeve with an opening on one end. The 2 inch sleeve is able to expand drastically for a snug fit regardless of your size. The minuscule size of them make them the perfect travel toy. Use as a solo male masturbator, or as a couples toy where the lady treats her man to a sensual hand experience for the pleasure of both. TENGA Hard Boiled Eggs come in 6 different unique internal textures with a lubricant for easy use included.
