The easy Ona Cup Tenga Egg. Just open the Egg and enjoy your quick and easy fun where ever you are. Made by Tenga, the company behind countless innovative products. An original from Japan.
I bought this egg at the same time as the Wave Tenga Egg. They felt similar during use; However, Wave has more texture inside and will give you more stimulation than Twister. Twister is OK if you want to last a while, but if that's your goal, Thunder will be even better for you.
