The Egg Sheller is a cool device that helps you de-shell hardboiled eggs. Hard-boiled eggs can often be annoying to peel especially ones that are a bit overcooked or a bit undercooked. This tool helps you get the shell off in one nice peel. Simply add a little bit of water and drop your hardboiled egg inside. Give it a good shake and pull out the egg. The shell will slide right off and it's one of the most satisfying things you'll experience.
