Queen Marker Pen
Use this Queen Mark Pen to Mark your queen. Record the age of your queens.
Follow the international queen-colour code: White in 2016 and 2021, Yellow in 2017 and 2022, Red in 2018 and 2023 etc. This system has been around for decades because it’s uniform, consistent, and lets a beekeeper know the age of the queen while making it easier to spot her in a crowd.
