If you like a snug, ribbed, flexible sleeve, The Tube has an open end that allows for easier movement on a shaft. Shaped like a tornado, the inside column can give two very different sensations depending on which end is penetrated first. The Tube's clear translucent elastomer material lets you see what's happening on the inside, and the hand-friendly shape is... handy. When a hand is slippery, the thicker ends help you hold on, and little light nubbles assist the grip. We strongly recommend the FleshLube water based lubricant for the long-lasting formulation and easy clean-up. You can use other water-based lubricants, but they'll soak into the material fairly quickly.
If you want a less snug fit, consider the Maven or Tenga Spiral.
