These are 3D Tunnel Markers to use with the new Subterranean Assault detachment 40mm in Diameter and only a few mm tall so it won't interfere with model movement.
EACH Set comes with 6 markers. Buying two sets at once gets you a discount.
Minor cleanup might be needed with a hobby knife.
Colors are Tan and Black. Recommend black if you plan to paint them and tan if you don't plan on painting them.
