Handling is very easy. Water into invert lid in the shape and in the freezer.
Unfortunately, they can be reluctant to get out of shape. So best short dive in filled with lukewarm water basin and then hope that they can bring healing out of shape. Gladly are 2-3 while the break.
Pour on no case with hot water, otherwise the ice breaks almost always!
12 Are my almost too little, because people always want to drink from it. One can also make cola or juice, but then degenerates into a mess when a melt in your hand you the same. So rather use of water and for a shot.
Have Fun!
