Disappointed with my Ork Glyphs

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.
