Also known as Wartenberg wheels, these devices are great fun for sensation play. Run lightly over the skin for tickling, prickling sensations.
Especially effective on skin warmed by play or sensitive areas. Combine with a blindfold for mind games and an even more intense sensation.
Classic design and (as always) superb quality. Use with a blindfold and try using from the freezer. Play with pressure, speed and body position. Upgrade to include case highly recommended.
