These dice are blood-red, super shiny and SHARP. You do not want to take these through customs. I'd recommend a rolling mat, as not only will they scar a soft table, they don't roll super well on smooth surfaces - you need something spongy, or a dice tower, which DnDice handily provides, and I can personally attest their quality. Top notch quality as always from Grady and Porridge. Stabby bleedy murder dice.
