Sold singly. Scarab Jade d6 with gold numbering. These are standard 16mm 6-sided dice and are sold individually.
Beautiful dice, delivered promptly and accurately. My only complaint is that I needed to search first for single dice and then search again for the matching set to get a set +3d6 extra. This was harder than it should be because the related suggestions don’t go to the most useful products. Also, if you do this- pick your single dice first, b/c the options are more limited.
