This One Handed Queen Catcher is designed to make it easy to catch the queen once you have found her. It has a built-in safety stop that prevents you from applying too much pressure and killing the queen, and its one-handed design makes it quick and easy to use.
The grid is opened and the queen is allowed to enter the area. When she is safely on the padded plunger, the grid can be slid closed with your thumb. The queen can then be slid towards the grid with your finger from inside the tube. The goal is to gently press the back of the queen against the grid where she can be marked with a queen marking pen.
