Soothing as gentle ocean waves, Placido rubs along sensitive skin with very little friction but surprisingly arousing pressure. Ideal for external or vaginal massage as you explore exactly where your sensitive arousal nerves like to be caressed. Placido is relatively heavy, and at first feels cold, both of which add to the internal awareness sensation connecting your mind to exactly what is being massaged. Not ideal for anal penetration as slippery hands can lose track of Placido's smooth surface. Color: Blue. Material: Hardened Pyrex glass. Size: 1.75" at widest point, with total length of 7.75". Cleaning & Care Instructions: Warm soapy water. Careful not to drop, and don't use if you crack the glass.
