Silicone rectal / anal dilators were designed by pelvic floor specialist, Dr. Amanda Olson. Our dilators are made from smooth, medical-grade, 100% BPA-free silicone and shaped for maximum safety and comfort. The anal dilators are for both recreational and medical use for men and women. These may be purchased as a full set of 8 gradually progressing sizes, in four packs of small, medium, and large, or individually. All anal dilators ship in discreet packaging to maintain privacy.
