Queen Marking Tube
Queen marking tubes are designed to quickly and safely mark your queens. They are made with clear plastic so you can see exactly where your queen is, and the plunger has foam on the end to cushion the queen. Carefully push her up against the screen so you can easily place a mark on her thorax with one of our queen marking pens (sold separately). This is a larger marking tube that measures 1-1/2" wide.
