The TENGA EGG is made of a super-stretchable material, and can completely cover a 500ml plastic bottle. They are designed to give the option of stretching for complete coverage or limiting stimulation to only the head of the penis.
To use, remove the shrink wrapping and open the egg-shaped case.
Next, apply the lotion provided in the case to the inside of the soft EGG.
Place on your shaft and enjoy the super-stretchable material to stroke and twist as desired!
