Enjoy this smooth, waterproof mini vibe with its angled, pointed end for focused stimulation--the petite Rivet is designed to nestle into the body for pinpoint pleasures. Or insert it shallowly (though it's not anal-safe)--or for a different and less focused feel, hold the length against the body for more coverage. Takes one AA (not included); to insert the battery, twist so the arrow points to Open, then twist again toward On or Off to operate.
