3mm Miyuki Bugle Beads in color #1, Silver-lined Clear.
These are, indeed, both clear, and silver-lined 😉 .
They come in a tube, stuffed as full as I can get it with 9+ grams.
There are around 83 beads per gram, so approximately 747 beads per tube.
The hole is about .65mm in size.
These are Miyuki Japanese bugles.
