The Men's Max Feel Spark Onahole Hard (Open Type) is a see-through masturbator toy that has a non-vacuum, open-ended design (so you can pump faster with less resistance) but with a firmer grip, so you get the best of both worlds.

Like others in the series, the toy has an innovative self-lubricating gimmick. Just add water to enjoy a wet feel that makes insertion a joy from start to finish, and which brings out the full texture of the vagina. Being open-ended, you don't get a vacuum sensation and so can pump harder and faster.
