These are 3mm laser-cut perspex tokens, engraved on both sides. They're intended to be used when playing Battlefleet Gothic, and are sized appropriately. Blast markers are transparent orange, others are gloss black.

Please note that the tokens in the image have had the engraved details on them filled in with wax crayons (I also added a little colour to the attack craft squadrons with acrylic paint). Tokens are sold without being filled in this way, but it's quite easy to do, as shown on the 2nd image.
