Paul Beakley You can get them in her Etsy store!
Adam D What Paul said. You also need a dice cup to roll them so you don’t shred your hands, but then the dice quickly destroy each other as they bounce around the cup. I used mine for one game and by the end they looked like they’d been through a war. Which looks cool! But they are a better artifact than a tool.
This is not to knock Amber. They are exactly as advertised and I love them. But I use her chamfered gaming dice instead, which are the best sixers ever made, period.
