The Mysterious Cube

Remember when you had to find a bunch of meteors to find all the presses? No more! Now meteorites come with a Mysterious Cube.

I wonder what happens when you break it (without Silk Touch)...

You can also make a replica: the Not So Mysterious Cube.

Recipe

While you can't make a Mysterious Cube, you can make a replica: the Not So Mysterious Cube.
