This Canada pony has large pieces of glass that fell into the mould just before pouring and thus have been melted forever into the dome surface. Photo collage tells all. One popped bubble on the base edge in the way of damage and that's from factory. Dometop is much more impressive in person when you can actually feel the deep crevasses in between the chunks. Satisfaction is completely guaranteed with this one and all my insulators. $50 shipped USA/CANADA, other countries I will assist with shipping. Now $30 + shipping.
