As one that enjoys having her nipples pinched and played with, I'd say these simple clamps are perfect to put in for solo or partner play. The cushioned tips are thick enough so that the metal is not poking through. There is a circular ring to adjust the tightness of the clamps on the nipple. Since there is no weight on the ends, they are great to wear around the house or under the shirt on the way to a "hook up" :).

The clamps are small enough to put in a pocket, handbag, and for travel. The clamps are metal with thick rubber tips which does not have an odor. For an added twist on sensory play, put the clamps in a bowl of hot or ice water.

The clamps are compact and easy to fit in bags. They are pretty easy to put on and can be worn under clothing. Though I haven't tried yet, they may also work as clit or outer lips clamps. The clamps could work on various nipple sizes.
