In a recent post I mentioned the thickness of the Ork Glyphs I recently ordered from Forgeworld.
Well as I suspected might happen they proved difficult to cut apart and I managed to crack the glyphs.
I thought they would be like the Purity Seals which are attached by a very thin resin, these are mounted on 2mm thick resin which also means they look less effective when stuck to vehicles.
I might try and sand them down and see if that makes a difference.
