Using this egg cracker and separator is a breeze. First, place an egg on the tool. Then, press the button gently, and the eggshell will crack open quickly. To separate the egg white from the yolk, just pour the cracked egg into the egg white separator included in the package. When using, make sure not to press the button too hard to avoid splashing the egg. After each use, clean the tool with warm, soapy water and dry it thoroughly. This will keep the tool in good condition and ensure its long - term use.
