The strange name when translated into English will perfectly describe the design of this onahole. "Rina" is the name of the character on the box while "Sujiman Kupa" is Japanese slang for "camel-toe"!

As the name suggest, this onahole has a camel toe exterior entrance which covers the interior dual-layer design. Upon spreading the camel toe outer walls apart, you will find a very detailed crafted inner-hole design with all kinds of realistic bumps, folds, and mini G-spot structure.

Compared to the Sujiman Kupa Roa, Rina has more refined textures to that of Roa. The beginning of Rina is very similar to Roa in textures leading to the G-spot. However Rina's middle section changes to smaller ribs for a gentler, mellower stimulation. This mellowness leads to the cervix structure which has a dual purpose. You can stop at this structure and use it as a penis head massager with a rotating motion or go through to experience a tight sensation at the end of the tunnel.

This dual-layer design features a soft outer material that simulates the softness of a young woman's skin while inner material is more stimulating giving you a great feeling. This combination of gorgeous appearance and great stimulation from the dual-layer design makes Sujimon Kupa Rina a great buy for Kupa Roa owners.
