This a single 30mm d6 die that part of the Festive line called Waterlily. It has swirls of purple, blue, green with white pips. Thirty millimeters is a little larger than 1".
The particular die in the photo are just one of the dice that I have ordered. Thus, the actual die that you receive will be the same colors but may have slightly different markings. No two dice will be exactly identical.
