I love these cube beads from Toho.

These lovely "Raku" beads have a matte finish that gives a subtle glow. The colors are purple and blue, mingled as in a fine ceramic vase.

The effect is lovely.

Notice that these holes are quite large, relatively speaking. You shouldn't have any trouble using these with most worsted weight yarns.

Packaged in the smaller containers with about 20 grams/ figure on roughly 12 beads per gram
