The Bcurious Premium is ergonomically designed; each surface and curve is designed with the specific intention of pleasure. The broad curves and pointed tip means that this toy can be used to create broad or pinpoint vibrations customized just for you. The pinpoint accuracy leaves nothing to Bcurious about when used for clitoral stimulation while the broader angles fit wonderfully around the labia. The firmness of its material makes it great for grinding against. This massager is exclusively for external stimulation. The Bcurious Premium has a blue backlit push button control, the lower section of the button turning on the massager, while the upper button sends the Bcurious Premium through its 7-functions, therefore the sensations and pulsations never stop. With up to 60 days stand-by and being USB rechargeable the Bcurious Premium is ready to go whenever curiosity gets the better of you. Wash the Bcurious Premium in warm soapy water and rinse thoroughly ensuring the adaptor cover is properly closed. Take special care when washing the areas around the seam.
