These cone-shaped beads are 11mm at the widest to 6mm at the end.  Holes are drilled down the center of the length.
As far as finish goes, they are not matte and not very glossy.  They are very inexpensive so would be useful where a large number if filler beads are required.

The photos above are a little brighter red than the actual and they have a glow from within.

There are 80 beads on this long strand.

Price is for a 4-strand lot.
