Taking a break from literal gem dice to show off the best d4s ever made. Not only are these not caltrops waiting to pierce slippered feet at night when a stray one happens to be right where you're stepping in a rapid trip to the bathroom after a night of drinking way too much tea while playing RPGs, they also roll much better.
Whoever invented these is a genius.
...my wife and i have a lot of dice, all kinds; this photo includes perhaps one-quarter of our collection...
...without reservation, i'll vouch that my wife's role4initiative set (including their arch d'4) are the best-rolling dice i've ever played: perfect feel, easy to read, well-balanced, just ideal in-hand in a way that's difficult to describe until you use them...
...the only reason i haven't bought my own set is that i don't care for the colors and their typeface is pretty uninspired, but if all you care about is how they play, role4initiative can't be beat...
