2.8mm Miyuki Triangle Spacers in color #401, Opaque Black.
They are, indeed, opaque and black. ;)
These are a flat triangle shape with the hole through the center like a donut.
They measure about 2.8x1.3mm in size, with a 1mm hole.
Great for stringing, or as texture in bead embroidery and beadweaving.
You will receive 8+ grams in a short tube.
There are about 75 beads per gram, so you'll get around 600 beads per tube.
Please keep in mind that this item is sold by volume, not weight, so counts are approximate.
Happy beading!
