The Horn is a simplified version of the Unicorn Horn. It has a smooth flared base which works great with an o-ring style harness. It is perfectly tapered and smooth available in a shimmering mixture of silver and gold. 6 1/2 x 1 5/8 *** this item may be ordered SOLID or WITH a CAVITY designed to accomodate micro, mini and bullet vibrators. Please note: Including a cavity in your sculpture will result in less rigidity at the base. (It will bend a little unless you have a vibrator inserted.)***
