Recomended by many therapists & health proffesionals, we created Sh! Dilators as a response to the hard plastic versions offered by NHS, which many women told us were too hard and unyeilding. Set of 4 body-safe silicone dilators, graduating in size: Dilator 1 - 2.8 inch (71mm) / 0.53 inch (13mm) Dilator 2 - 3.9 inch (99mm) / 0.63 inch (16mm) Dilator 3 - 4.75 inch (20mm) /  0.75 inch (19mm) Dilator 4 - 5.75 inch (145mm) / 1 inch (25mm) Each dilator has a small pocket in its base which holds the small bullet vibrator (strong, rechargeable & waterproof offering 10 different patterns) Vibration can help to relax tense nerve-endings, and it can make dilating experience less 'medical' Dilators can be part of the treatment for Vaginismus, Vulvodynia, After-effects of Pelvic Radiation, Vaginal Atrophy, Lichen Sclerosus & Pelvic Floor Dysfunction Please Note: We do NOT recomend self-diagnosis & urge all customers to see their health provider before starting dilating.
