These dice are definitely not engraved. I have another set of engraved opalite dice, and these are printed on. I'm in contact with Massdrop Customer Support now about this. Will update.
TezaYeah please let us know. This should be an immediate refund, there is another drop on this site that ran for cheaper where the die were not engraved. I got those and decided I wanted another set that was indeed engraved, but I got the same ones.
