The Imirie Shim works well to add extra space between boxes. You can use this for medication, or introducing a new queen. It ships with no notch by default, but if you want a notch we can cut one in. The notch will give you an upper entrance during the honey flow. Note: The bees will burr this up so don't leave it on for long.
Shipped plain by default. If you want a notch please leave a note in the comments section when placing your order.
