(what is an onacup?)

original: "Special HARD Edition! With deep and intense suction combined with a hard tightening action The interior lining is created with a state-of-the-art elastic material for a more intense stimulation. The one-way valve creates a superior suction, and the newly developed "moving frame" lets you experience a new kind of stimulation like nothing else on earth! Let the TENGA BLACK guide you to a harder and more intense deep throat experience!"
We say: sucks great and is nice and tight.

Onacups are ment for single-use and can only be used a few times.
