The set includes three different sizes (small, medium, and large), allowing you to train your body to accept larger and wider toys! Enjoy the variety of textures this set offers to explore more sensations. Each plug is firm and flexible for comfort and pleasure! The small plug has a ribbed texture. The medium plug features a spiral line wrapping around the shaft. The third and largest has a bigger head and ends in a large, round base. These curves allow the sphincter to experience stretching and contractions multiple times with each insertion! Once you adjust, you will love the sensation! The softness of the plugs made from premium silicone is due to quality materials that are free from phthalates, latex, and hypoallergenic.
