Delica seed beads are extremely uniform cylinder beads created by Miyuki in Japan. Delicas come in a variety of sizes and a wide range of hundreds of colors. They can either be smooth or six-sided (hex-cut). Delica beads are preferred by artists for loom work or off-loom bead weaving projects that require an even, symmetrical appearance. Delicas have the most extensive color palette of all the Miyuki seed beads.
