Pipedream has brought us the Icicles No. 31, a familiar design that is quite effective for G-spot stimulation. The No. 31 doesn't stop at G-spot stimulation, it can be used for P-spot stimulation too, or as a vaginal or anal probe. Being made from glass it is completely non-porous and perfect for temperature play. A tried and true deign, the No. 31 is the perfect glass dildo.
