A collection of objective markers. There are 2 sizes 1 Inch and 40mm. There is a 3 inch outer ring on each marker. The outer most edge is 3 inches from the edge of the objective marker the inner edge is 3 inches from the center of the marker. Outer ring is only 1mm thick so it can be slotted under terrain etc without interfering with anything

There is also a version of each with a hole for a 3mm by 1mm magnet and a cap. So you can make a more interesting objective using the cap, which can then be easily removed if a model needs to stand directly on top of it.
