These are used to introduce a new queen into your colony.  Candy must be added to restrict her from escaping until the workers free her.

Candy can be made with powdered  sugar mixed with honey or HFCS. Mix until you make a paste with consistancy of Play-Doh.

There is a hatch to release her early.

I would consider these as a 1x use.  That is why they are inexpensive.

Due to fees and shipping costs. I must sell these in a lot of 15  to make selling them reasonable.
