The Tantus Magma is a fantasy dildo that looks like flowing lava: molten drips run down the shaft, with a glossy and matte finish that gives the texture something to catch on. Tantus shapes it for G-spot and P-spot play, and it works in a harness.
This is the 7-inch, medium-firm version in silver: 1.5 inches wide with 7 inches insertable. Because the Tantus Magma is 100% silicone, you can warm it in hot water for temperature play and boil it to clean.
