Double Ball-Rは、モーターや振動プログラムを使わずに、振動と震えを生み出すディルドです。多用途で革新的なこの製品は、内部の2つのボールの自然な動きを利用して、ユニークで圧倒的な感覚を生み出します。常に変化する刺激を求める方に最適で、幅広の吸盤ベースにより、アナル、膣、またはストラップオンベルトでの使用に最適です。肌にやさしい柔らかいシリコン製で、防水コーティング、人間工学に基づいたデザイン、波状の構造が強い感覚をもたらします。直径：約2.2cmから3.8cm。
Wasn't sure the two internal balls would actually do much, but the rolling motion gives a surprisingly deep rumble without any buzzing. Being able to use it hands-free and just let the movement build is a totally different feel.
The whole idea of no motor sounded gimmicky to me, but those two inner balls really do move with you and the rolling sensation is unlike anything I've tried. It's surprisingly quiet too, which I didn't expect from something with no battery at all.
Wasn't sure about the whole no-battery thing, but the two balls rolling inside actually create this deep rumbling feeling that's way more intense than I expected. Ended up using it way longer than planned.
