Now made of a thicker, more durable material for longer-lasting fun. Different Strokes from Different Yolks! The TENGA EGG Series may look small, but their super-stretchable material can fit men of all sizes. The external designs of each EGG reflect the internal details within them. A huge upside is the fact that the Tenga Egg is very easy to clean up. No real mess… you can put the egg back in the shell and then throw it away.
