Toho 8/0 Hex Japanese seed beads have a very consistent shape and size and are available in a large selection of colors and finishes. Hex-cut Delica beads are designed to have a larger hole than other seed beads that allows for even more pass-throughs for thread. The larger hole also creates lighter beads which give you more beads by weight. The Miyuki hex-cut beads come packaged in a 23 gram tube.
