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.

The special wetch (wet touch) technology of the toy allows it to self-lubricate just by adding water, which also enhances sensitivity and brings out all the fine and subtle textures of the inner tunnel.
