The best quality for the best satisfaction! The Vibratex Thumbelina is made of soft jelly material and has a motor that doesn't know when to quit. If you are looking for the best in quality then you have found it. The Thumbelina has a usable length of 3.875in with a varying diameter of 1.25in. The shaft is covered in tiny nubs and gyrates with the push of a switch. The clit teaser has rows of nubs with a large probe on the end for more direct contact. A motor inside of the bullet allows for more power where you want it. Simply slide the switch to the desired speed and the teaser will take you away. The controller base requires four AAA size batteries (not included) to provide maximum power to these amazing motors. The one and only Vibratex!
