This is the eight sided die (D8) from my 'Starry' set.
It measures 14 mm (0.6 inch) across the opposing faces, and 25 mm (1 inch) from tip to tip. This design is hollow and was optimised for printing in steel or any of the other metals. In steel this die weighs about 6 grams. The die is well balanced and gives a fair roll.
For all the other dice in this set, please have a look at the 'Starry' category
in my shop.
