The TENGA EGG Series features super-stretchable material that accommodates nearly any size, with external designs reflecting their internal details. Among the various options, the Tenga Egg Spiral offers a spiral staircase-like structure for invigorating stimulation with firm elastomer. These single-use, disposable products are simple to use: peel the wrapping, open the shell to access the egg, add the included lubricant, and apply around the entry for smooth insertion. After use, the egg can be sealed in its casing for disposal
