SIZE-8 CRYSTAL AB Delica are perfectly cylindrical seed beads:

Delica beads are machine manufactured in Japan by Miyuki. They are one of the most popular seed beads. They have large holes so you can easily pass multiple strands of thread through them. Their uniformity of size and shape makes them a perfect fit for almost any bead-weaving project. They easily fall into place in popular peyote stitch and brick stitch. Delica seed beads are as tall as they are wide. They are perfect for loomed pieces and are an excellent choice for curved pieces. The large holes make Delicas easier to work with when creating knitted or crocheted beaded projects.
