Dice King Games Design is running a Kickstarter campaign for dice with multiple iterations of 1-6 on them.
From the campaign:
Atomic Dice are unique 18 sided and 24 sided dice laser etched 1-6 with pips 3 times on the 18 sided and 4 times on the 24 sided. That’s right these are d(3X6) and d(4X6) polyhedron dice made from 6061 aluminum metal. The d18 and d24 are the rare polyhedron dice and what I have done is taken the standard d6 with pips concept and multiplied it 3 and 4 times onto one die.
