Logo is different so I guess it’s not affiliated with the board game cafe in Liverpool?
They sell cakes but edible d20s on top would be sweet.
As someone who lives in a hot climate, this sounds… sticky.
Even after zooming in on the image there don’t appear to be numbers on the dice? Maybe imprinted but my experience with hard candies doesn’t indicate they’d take that delicate of a shape very well.
EDIT: Found higher quality images, yeah the numbers are imprinted but super hard to read even in promotional photos where they’ve pretty obviously taken the best ones from a batch and put them clearest numbers up.
Anything is edible if you believe in yourself.
Watch out. If you eat these too much you might get dicebetes.
