D4 Shell Dice

 

D4 Shell
It's a Truncated Sphere D4 without faces! Have a look to a newer version here.
The idea of keeping only the round part of a truncated sphere die when the numbers are located on vertices or edges is from Clsn (check his D9 for instance).
The thickness is 2 mm and the diameter 25mm (a smaller version for Gold Plated Brass is now also available). Since it does not contain a lot of material, this die is quite affordable.

All the D4: 
  - Truncated Sphere D4
 - Concave D4
 - D4 Shell

A version numbered from 2 to 5 is also availble.
