Almost all beads in this listing have some black showing at the stringing hole. This does not show through to the surface of the bead and should not affect its use in most designs.
The 24 Round beads measure 10mm with a swirled pattern. Silver foil inside is very apparent when highlighted by a light.
The 3 cylinders measure 10 x 20mm and also show a swirled pattern. Finish is similar to the rounds....
Both these variations show a more subtle silver glow than some other silver-lined beads.
