Lovetoy Glow in the Dark Glass Dildo Dark Twilight

Glass that glows in the dark once it has spent a few minutes under a lamp, and then keeps glowing for the rest of the evening. Underneath the trick is a proper toy: solid glass, a smooth profile and enough weight to press where you want it. Charge it under any light source, switch off, and the shape is suddenly very easy to find. The largest of the Twilight models.
