Or just a run of the mill? I like it better than a lot of the named ones I have. lol The color is slightly off I didn't realize I had a wrong custom wb going on.
+1 have seen this type in several LFS. They called in a convict. However there are true higher end convicts with actual positive and negative body stripes. Cornbred and golden basket have a few. Not the overlay on raised bumps most of the more affordable ones have. Many un named chalices are gems in a tank.
If you google convict chalices you will see the true named ones and see they warrant the price tags. They do not look real.
