The Explore 3.5" Plug in Platinum Premium Silicone gives you full access and an unobstructed view of your bottom's back door. The textured dual-finish exterior of this tunnel plug slides in and holds firm to keep that ass open for action and a heavy-duty flared base keeps Explore safely in place while you insert fingers toys and more through the wide hollow center. Explore's ribbed stem provides extra pleasure with every movement and the open base can also be used for liquid play with your favorite funnel nozzle or tube toy.
