Question: I wanted to know if they come with four or just one to count at least up to 64 rounds?

 Answer: Only one set is included per piece ordered. However, they cointain 20 beads so that you can tie them onto your bead bag with 4 beads seperated on the other side. This way you can use the 4 beads to count sets of 16 rounds up to 64 rounds.
