The summary says it all. It's a very simple texture pack that updates the Lucky Block textures to look more like Jappa's default Minecraft texture pack. Nothing more can be said. I haven't tested this pack on older versions, but I think that it supports all versions of the Lucky Block mod, from 1.6.4 to 1.16.1.
