Many years ago, mini bicycle cards height were 2.5 inches. The same as Poker size width. These newer
mini cards are slightly shorter.
I bought a deck of these to do Diamond Jim Tyler's small
card effect, and had to adjust my handling due to the mini cards smaller then needed side. Not
exactly an issue with the product, but that's what I need it for.
Also, the tuck case is
almost too small for the deck. I literally had to tear the case to get the cards out.
