In Alumide (and manually varnished)
Sorry, I do not customize products anymore...
This is Rounded D6 Die
of 20 mm (it is bigger than regular dice that are generally 16 or 18 mm).
It is hollowed (2mm shell) but still contain the "support material", keeping it relatively heavy.
Opposite faces sum to 7 (well, except for the blank die). You can choose between a blank die, two numerical dice (standard and roman numbers) and two dice with pips (regular arrangement or arranged in circles).
