The pink satin glass beads are drawn and faceted tubes of glass with what look like silky fibres but may be actually drawn/stretched bubbles within the glass and the pink may be the result of a later process of soaking in a coloured dye that penetrates the tiny apertures by capillary attraction.... probably Czech? Others may have a different idea...i’ve seen them in a pale blue and pale green as well-
The coloured ones dont appear Krobo to me but some glass and some perhaps plastic?
