PentaBelt D4 (V2). An interesting alternative.

This die may be used instead of the D&D D4 lightweight, which is both difficult to read and pick up. The 'PentaBelt' is about the same size as a D&D D12 and similar in weight to a D20.  Quite unique in appearance, the new die is numbered only on the pentagon faces, with the uppermost displaying the result.  I believe the die to be fair, even though it is made up of two different shapes, an equilateral pentagon and 'golden ratio' trapezium.  Rollability is much dependent on the surface.

 

Many thanks to Robert Austin for getting it out there, Adrian Rossiter for expert coding (Antiprism) and Vincent at The Magic Shop for numbering the die.
